Features & Benefits

Feature Benefit
Shortwave Technology

HN infrared heaters utilise shortwave technology to provide the most economic means of heating intermittently used buildings or of providing spot heating in an otherwise unheated area

Halogen Lamp

The high quality infrared halogen lamp produces shortwave radiant energy that can pass through the air with virtually no losses until it is experienced as warmth by people entering its target area,

The lamp will be 100% effective the instant it is switched on.

Gold Lamp Filter

The state of the art gold lamp filter emits a soft pink/orange glow and converts a ‘best in class’ 95% of its output into useful infrared energy

The soft pink/orange glow is generally acceptable in all installations including churches.  This was not the case with the ruby filtered lamps from a previous generation.

Open front design

25% increase in heating efficiency compared with glass fronted heaters

Long lamp life

An average lamp life of 7000 hours operation means minimal ‘down time’ and a corresponding saving in the cost of spare lamps

Precision parabolic reflector

The highly polished and precision designed parabolic reflector efficiently focuses the shortwave energy at the target area ensuring maximum benefit from every kW consumed

Robust aluminium case

The HN series is smart enough for commercial applications but robust enough for demanding industrial use.

Safety Guard

Prevents accidental contact with the heat lamp. The guard is close spaced to allow the heaters to be use in squash courts

Mounting bracket and four M6 threaded holes to facilitate suspension

A choice of mounting systems allows the heaters to be positioned exactly as required to focus output precisely on the target area.  The brackets allow ‘up and down’ and ‘side to side’ adjustment.

Rear mounted terminal enclosure on two and three lamp models

Allows lamps to be switched individually and provides a simple means of converting three lamp models from single phase to three phase

How it Works

HN infrared halogen heaters use quartz heat lamps to produce shortwave energy.  This energy is directed at the required target area by a precision designed parabolic reflector.  Shortwave energy moves in straight lines from the reflector to the target area without heating the air in between.  However once the energy is absorbed by solid bodies, which could be objects or people, it is experienced as heat.

Shortwave energy cannot be blown off course by breezes and draughts and is ideally suited as a heating method in intermittently used buildings and for spot heating within a larger unheated space.

HN infrared halogen heaters are supplied with adjustable brackets for wall mounting.  Alternatively the heaters can be suspended using wires or chains.  Where suspension is required, our HSK suspension kit comprising 4 hooks should be used.

As HN infrared halogen heaters are 100% effective the instant they are switched on, there is no need to pre-warm an area.  For this reason it is a good idea to use control devices that ensure that an occupied area is not heated.  Typically these would be time delay switches or movement sensors.  See the ‘controls’ tab for full details of the BN Thermic range of halogen heater controls.

A brief explanation of a halogen lamp

To produce shortwave energy a very high temperature is required.  This is achieved by centering a tungsten filament in a quartz tube.  The tungsten filament operates at a very high temperature and without the presence of a halogen gas; particles from the filament would evaporate from the filament and be deposited on the relatively cooler inner wall of the tube causing blackening and severely reducing lamp life. 

The presence of a halogen gas gives rise to a phenomenon known as the halogen cycle.  A chemical reaction between the halogen gas, tungsten and oxygen creates tungsten oxyhalide molecules which, in a vapour form, migrate from the inner wall of the tube back towards the filament where the high temperature breaks the tungsten oxyhalide molecules apart.  At this stage the tungsten atoms are re-deposited on the filament whist the oxygen and halogen atoms move back towards the wall of the lamp allowing the cycle to repeat.

The halogen cycle allows a lamp to operate at high temperatures without blackening for several thousand hours.

Controls

HN infrared halogen heaters heat people directly without the need to build up and maintain a body of warm air.  For this reason thermostatic control is rarely appropriate.  Applicable control falls into the following two categories.

  1.  Intensity adjustment
  2. Devices to reduce running costs
  3. Multi-heater controls

 

Intensity Adjustment

CS-2 Controller

CS-2

CS-3 Controller

CS-3

CS-2 and CS-3 Controllers

CS-2 and CS-3 Controllers are for use with two and three lamp models and allow the lamps to be switched individually.  This allows the user to run a heater at full output in very cold conditions but reduce the output as the ambient temperature rises.

 

Controller Heater Settings
    High Medium Low
CS-2 HN2-3000G 3kW N/A 1.5kW
CS-3 HN2-4500G 4.5kW 3kW 1.5kW
CS-3 HN2-6000G 6kW  4kW 2kW

The controllers should be wall-mounted in a convenient location and hard wired to the heater.  By using suitably rated contactors    a single controller can be used to provide flexible control for a group of heaters. 

                                          

VR-2 Dimmer

VR-2

VR-2 Dimmer

The VR-2 dimmer can control the density of the output from infrared halogen heaters up to 3kW.  A simple panel front knob provides 30% to 100% adjustment.  It also proves a convenient means of isolating the heater with a definite ‘click’ to off. The VR-2 is IP55 rated.
 

 

Devices to Reduce Running Costs

TS-6 Push Button Timer

TS-6

TS-6 Push Button Timer (pre-programmed time delay)

The TS-6 is a compact surface-mount, weatherproof device which will energise a heater or heaters for a pre-programmed period between 2 minutes and 2 hours.  Once this period has elapsed the heating will automatically be switched off until the button is pushed again.

The TS-6 can switch loads up to 3kW directly and is touch activated for easy operation.

 

TS-5 High Capacity Soft Start Timer

TS-5

TS-5 High Capacity Soft Start Timer

The TS-5 timer is designed for direct switching of halogen heaters with a combined load of up to 6kW.  The time delay period can be adjusted from 5 minutes to 70 minutes and once this time period has elapsed the heating will be switched off automatically.  The built-in triac provides ‘soft start’ increasing lamp life by up to 10% and reducing stress on the mains supply.  The TS-5 includes terminals allowing the device to be connected to a remote programmable timer and/or a thermostat.

 

WH-402 Movement Sensor

WH-402

WH-402 Movement Sensor

The WH-402 is a compact, surface mount, weatherproof device which can detect movement up to 12m from its mounting position in a 180° arc.  Both distance and angle of detection can be reduced.  Once movement has been detected the heating will be switched on.  If no further movement is detected within a pre-programmed period (between 5 seconds and 18 minutes)the heating will be automatically switched off.

The WH-402 can switch loads up to 3kW directly and larger loads via a suitable contactor.

Multi-heater controls

A MC1 control box provides variable output control of halogen heaters from a single point.  This approach allows the intensity of heat to be adjusted by means of a simple wall-mounted controller enhancing comfort and improving economy.

Each system must incorporate one MC1-P primary controller and a wall-mounted controller (either CS-2 or CS-3 depending on the heaters being controlled.  For larger installations additional secondary controllers (MC1-S) will be required.

Controlling HN2-3000G (3kW) Heaters each with 2 lamps

A CS-2 wall-mounted switch will control up to six heaters.  The CS-2 allows the heaters’ lamps to be switched individually meaning that outputs of 1.5kW or 3kW can be selected.

Control of HN2-3000G 2 Lamp Heaters

Control of HN2-3000G 2 Lamp Heaters

For larger installations up to eleven secondary control boxes can be connected in a control daisy chain with each controlling up to six additional heaters..
Controlling HN2-4500G (4.5kW) Heaters or HN2-6000G (6kW) Heaters each with 3 lamps

A CS-3 wall-mounted switch will control up to four heaters.  The CS-3 allows the heaters’ lamps to be switched individually meaning that outputs of 1/3, 2/3 or full power can be selected.

For larger installations up to eleven secondary control boxes can be connected in a control daisy chain with each controlling up to four additional heaters

Control of HN2-4500G or HN2-6000G 3 Lamp Heaters

Control of HN2-4500G or HN2-6000G 3 Lamp Heaters

Additional Optional Control Devices

The following control devices can be linked to the primary control box.

Frost Thermostat (FST-IN)

If connected, the frost thermostat will override the settings on the controller or other connected control devices.  When the air temperature drops below the selected set-point, all the heating lamps will be switched on providing frost protection.

Economy Thermostat (RST-IN or RST-TP)

A wall-mounted thermostat connected to the primary control box will ensure that the heating cannot be switched on unless the air temperature has fallen below set-point.  There is a choice between a standard model allowing easy adjustment of set-point (RST-IN) and a tamperproof version (RST-TP).

Programmable Timer (PROTIM-7)

The PROTIM-7 will provide 24 hour/7 day programmable control.  This device has many features including optional PIN protection, automatic summer/winter time changes, advance to next programme, 1 or 2 hour boost and permanently on or off overrides.

Movement Sensor (WH-402)

This device will energise the system when movement is detected.  The integral timer has a range of 5 seconds to 18 minutes and the system will be automatically switched off once the selected time period has elapsed.

Timer Push Button (CS-5)

A wall-mounted push button will activate a rundown timer incorporated in the primary control box.  The time period can be set at 10mintes to 120 minutes and when the pre-set time has elapsed the heating will be switched off automatically.

This command can be cancelled by pushing the boost button for three seconds.

Master Control Button (CS-6)

The wall-mounted master control button, sometimes called the foreman’s switch, provides a means of switching the heating off and will override all other connected devices except a frost thermostat.

Selecting HN infrared halogen heaters

HN infrared halogen heaters provide instant direct heat to a target area.  The target area can be an entire building or a smaller area within an otherwise unheated building.

As a guide to selection please follow the following example.

Example

Use infrared halogen heaters to heat a well- insulated community hall 15m long by 6m wide with a mounting height of 3m above floor level.

Step One: Determine the total kW required

This is achieved by multiplying the square meters of floor area by the relevant Watts per square meter figure (see table one)

Floor area = 15m x 6m = 90 square meters

Select a figure of 200W per square meter from table 1 and multiply by the floor area

90 square meters x 200W per square meters = 18,000W (18kW) minimum kW output required

Step Two: Select heater outputs and mounting heights

Heater outputs and mounting heights
Use table two for heater selection.  To ensure a good coverage we suggest ‘footprints’ are allowed to overlap by 10 to 15%.

Taking the preferred mounting height into consideration, select the model that provides the required kW output using the minimum number of heaters.  Spacing the heaters evenly, plot the ‘footprints’ onto a sketch of the hall to ensure good coverage.
