Features & Benefits

Feature Benefit
Ceramic heat emitter

Provides virtually instant direct heat without the light associated with shortwave infrared heaters

Long life

Ceramic heat emitters have an average operating life well in excess of 10,000 hour meaning minimal ‘down time’ and a corresponding saving in the cost of spare emitters

Precision parabolic reflector

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

Robust aluminium case

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

Safety Guard

Prevents accidental contact with the heat emitter.

2- way angle adjustable mounting bracket

The standard bracket allows ‘up and down’ angle adjustment.  The use of the extension arm provided, allows both ‘up and down’ and ‘side to side’ adjustment meaning that the heated output can be directed as required.

 

How it Works

CH ceramic heaters use ceramic plaques to produce medium wave energy.  Assisted by a highly polished parabolic reflector, the medium wave energy travels in straight lines from the heater to the target area with minimal heat loss to the air in between. Once the energy is absorbed by solid bodies, which could be objects or people, it is experienced as heat.

As a ceramic plaque does not give rise to light output, a ceramic heater can be used in environments where the light output associated with shortwave halogen heaters is not acceptable. However, unlike shortwave halogen heaters, ceramic heaters are not recommended for buildings with high ceilings.

CH ceramic heaters are supplied with adjustable brackets for wall mounting.  There can be installed in a group to provide a total heating solution in buildings such as community halls or as an individual ‘spot’ heater to boost the temperature in a specific area such as a checkout station.

Once a ceramic heater is switched on it reaches its optimum heating temperature very quickly.  As a result significant pre-warming is not required. For optimum economy, we recommend that suitable control devices are used to 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 ceramic heater controls

Controls

CH 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. 

The following control devices are commonly use to avoid heating an unoccupied area and thus keeping running costs to a minimum

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

TS-6 Push Button Timer

TS-6

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 High Capacity Soft Start Timer

TS-5

The TS-5 timer is designed for direct switching of 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’ 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.

The TS-5 is rated IP55 making it safe for outdoor installation.

 

VR-2 Dimmer                                       

VR-2 Dimmer

VR-2

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.

 

 

 

WH-402 Movement Sensor

WH-402 Movement Sensor

WH-402

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.

Selecting CH ceramic heaters

CH ceramic heaters provide virtually instant direct heat to a target area.  The target area can be an entire building or a smaller area within an otherwise unheated building.

We do not recommend using ceramic heaters where the ceiling height exceeds 4m

As a guide to selection please follow the following example.

Example

Ch - community Hall 12m x 6m x 3.5mUse ceramic heaters to heat a well- insulated community hall 12m long by 6m wide x 3.5m high.

 

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 = 12m x 6m = 72 square meters

Select a figure of 240W per square meter from table 1 and multiply by the floor area

72 square meters x 240W per square meters = 17280W (17.2kW) minimum kW output required

Step Two: Select heater outputs and mounting heights

CH - suggested heater layoutWhere possible use a smaller number of 3kW heaters rather than a greater number of 1.5kW heaters. In this example the ceiling height is 3.5m allowing us to select 3kW heaters mounted at the recommended height of 3m whilst observing the required clearance above the heater.  The minimum number of heaters required is 6 (6 x 3kW = 18kW).

We would therefore select 6 x CH-3000 3kW ceramic heaters which should be wall mounted at 3m above floor level and evenly distributed.
