Thermocassette HP RADIANT HEAT CASSETTES FOR CEILING MOUNTING

Transcription

1 Electrical heat W Thermocassette RADIANT HEAT CASSETTES FOR CEILING MOUNTING 10 models Radiant heater Thermocassette is appropriate for heating of rooms with ceiling heights up to 3 metres where the walls are required to be kept free. Mounting the heater on the ceiling protects it from interference. They are therefore often used in public buildings such as schools and daycare centres. Thermocassette is also appropriate for supplementary heating over work stations such as a reception desks or cashdesks. Thermocassette also presents an effective protection against cold draughts. The cassettes emit long-wave heat rays (element temperature max. 100 C), which means that the air temperature in the room can be lowered whilst maintaining comfort and lowering heating costs. Thermocassette gives an even room temperature. Gives an even room temperature Corrosion proof casing of hot zinc-plated and powder lacquered steel panels. Colour: RAL 9016 The low surface temperature (max. 100 o C) make well suited for low ceiling heights. There is no risk of burns to the person(s) in this vicinity 300/600 is designed for mounting in false ceilings. For all other models, brackets for easy mounting are included, wire mounting set is extra Thermocassette is available in three models: 300/600, for false ceiling systems 304/604, splash-proof standard model with brackets 305/605, jet-proof special model with brackets, approved for rooms where there is risk of fire and recommended for use in agricultural buildings 16

2 Radiant heaters secure the comfort in the parts with lower ceiling in this open building. The installation has been supplemented with EZF (see page 28-35). provide a silent and pleasant heat without air movements. The architecht has made use of colours and shapes. The white and rectangular Thermocassettes are positioned between the red circles. The kendo room of the judo sports centre in Paris shows another aesthetical installation of Thermocassette. Ceiling mounted radiant heaters are automatically protected from interference. Twice a cordial welcome at the business centre in Göteborg. This shop for electrical items in St Denis, France, choose Thermocassette for their comfort and design. The heaters being recessed in the ceiling leave the walls free to expose the shop s merchandise. 17

4 POSITIONING, MOUNTING AND INSTALLATION Positioning To estimate approximately how many heaters are needed to heat a room the formula is: Min. number of cassettes = Area of the room [m 2 ] (Installation height [m]) 2 This formula is a basic estimation of the minimum number of cassettes needed to maintain the comfort. To calculate the right output for each heater, the total heating requirement must be calculated, see the Heating & energy handbook. Mounting 300/600 is designed to be mounted in false ceilings. 304/ /605 can be mounted in false ceilings, but are primarily intended for mounting on the ceiling or hung from wire. Wire mounting set, 74701, is extra. For minimum mounting distance, see Fig. 2. Fig. 1: Mounting in false ceilings min Radiant heaters Connection 300/600 is equipped with a 4 metres cable and plug, as well as special plugs that make joint connection very easy. 304/604 is equipped with a 1.8 metre cable, 230V~ plug included. 305/605 is equipped with a 1.8 meter cable, plug excluded.

Thermocassette can be used to compensate heat losses that occur near windows. Read more about temperature deficits near windows on page

5 REGULATION ALTERNATIVES Single heaters can be controlled by any Frico room thermostat. A group of heaters where the demand on heating comfort is higher is preferrably controlled by Frico electric heating regulator. ACCESSORIES RTE102 KRT1900 RTE102, electronic thermostat Can control the heat directly or via contactor when larger loads need to be controlled. Internal temperature setting C. Delivered with covering frame for recessed installation. Required connection voltage: 230V. Protection class: IP30. RTE104, electronic thermostat Can control the heat directly or via contactor when larger loads need to be controlled. Internal temperature setting C. Delivered with covering frame for recessed installation. Required connection voltage: 400V. Protection class: IP30. KRT1900, capillary tube thermostat Internal temperature setting o C. Required connection voltage: 230/400V (volt free contact). Protection class: IP55., electric heating regulator is a modern, variable regulator that adapts the energy use exactly to the demand and allows for full use of the advantages with radiant heating. The result is a warm heat and more energy efficient use. For use on 230V and 400V2~ (not 3-phase loads). Load 3600/ 6400 W. Slave unit S can be used at larger outputs (S handles the same outputs as ). Protection class: IP20.
