ESP Radiant Cassettes, Radiant heaters by BN Thermic

ESP

Radiant Cassettes

• Providing an extremely economic means of heating large commercial spaces
• Exceptional reliability – backed by 5 year warranty
• Attractive unobtrusive design well suited to modern facilities
• High mounting positions allows flexible use of floor and wall space and does not interfere with activities

Typical Applications

• Sports Halls
• Squash Courts
• Showrooms
• Community Halls
• Food Halls

The installed load must exceed the heat loss from the entire area. ESP black heat radiant cassettes are not ideally suited to
‘spot heating’ applications.

Features Common to all Models

• FIVE YEAR WARRANTY
• No draughts, noise or light output
• Robust steel case with attractive white epoxy finish
• Specially treated aluminium heat emitter
• Brackets for ceiling mounting and four fixing points to facilitate suspension

Optional Adjustable Brackets

ESP-B adjustable brackets can be used for both wall and ceiling mounting.  The brackets are designed  to allow the angle of the heater to be easily adjusted.

Selection and Installation

The total load of the selected ESP cassettes should exceed the heat loss from the building in cold conditions. The heaters should be ceiling mounted or suspended at high level ensuring that the space between the heaters is no greater than the distance between the heaters and the floor.

Black Heat Radiant Cassettes should be seen as an energy saving alternative to conventional space heating systems, they are not ideally suited to ‘spot heating’ applications.

Energy Saving

Black Heat Radiant Cassettes are the most economic heaters for buildings with high roofs for the following reasons.

• The gentle radiant effect means that the ‘experienced temperature’ can be up to 4°C warmer than the actual air temperature. This means that the thermostat can be set up to 4°C lower.
• The temperature gradient is negligible. Typically air temperature will increase by 0.3°C per metre above floor level. This figure compares to a typical 2.5°C per metre when using fan heaters.

Controlling ESP Radiant Cassettes

The recommended means of controlling ESP Radiant Cassettes is to select one of four control packages

Comfort control package
Programmable package
Programmable package with set-back
Flexible Package

All control packages are based on BN Thermic’s range of Hard Case tamperproof and vandal resistant electronic control devices. Hard Case’s tamperproof design ensures that only authorised personnel can adjust the temperature setting.

Comfort Control Package

The comfort package utilises the Hard Case HC-T2 tamperproof thermostat which should be wall mounted at approximately 1.5m above floor level. The thermostat will switch the heaters via a suitably rated contactor.

Programmable Package

The programmable package utilises the Hard Case HC-T2 Tamperproof Electronic Control Device which should be wall mounted at approximately 1.5m above floor level. The Electronic Control Device will switch the heaters via a suitably rated contactor. A 24 hour/7 day programmable timer (TIM-D1) will ensure that the heating system is not energised while the building is unoccupied (typically at night and at weekends). The programmable timer has a built-in run-down clock that is triggered by a remote mounted ‘boost button’. This feature will provide a temporary temperature boost for a predetermined length of time during a period when the system would normally be ‘off’. The boost command can be cancelled by depressing the ‘boost button’ for 3 seconds.

Programmable Package with Set-Back

The programmable package with set-back utilises the Hard Case HC-ST2 Tamperproof Electronic Control Device which should be wall mounted at approximately 1.5m above floor level. The Electronic Control Device will switch the heaters via a suitably rated contactor.

The HC-ST2 has two settings: high (comfort) and low (set-back).  A 24 hour/7 day programmable timer (TIM-D1) will ensure that the heating system operates at its low (set-back) setting while the building is unoccupied (typically at night and at weekends).   The programmable timer has a built-in run-down clock that is triggered by a remote mounted ‘boost button’.  This feature will provide a temporary temperature boost for a pre-determined length of time during a period when the system would normally be in set-back mode.  The boost command can be cancelled by depressing the ‘boost button’ for 3 seconds.

Flexible Package

The flexible control package utilises a Hard Case HC-ST2 Electronic Control Device switching a group of Black Heat Radiant Cassettes via a suitably rated contactor.

The HC-ST2 has two settings: high (comfort) and low (set-back).  The default setting is low (set-back).  The HC-ST2 incorporates a simple push button which changes the set-point from low (set-back) to high (comfort) for a pre-programmed period of time (30 minutes up to 7hrs 30 minutes in 30 minute increments).  Once this period of time has elapsed the Electronic Control Device will automatically revert to its low (set-back) setting.
