- EC fans
- There are four models of heat exchanger available:
- Copper/aluminium, ideal for low temperature systems
- Galvanised steel, for LPHW, LPWW and thermal oil
- Galvanised steel, for steam
- Galvanised steel, cross-counterflow
Technical details:
- Production plants, warehouses
- Builings connected to district heating systems or with wide temperature ranges
- Areas at risk of explosion
- Buildings with steam heating plants
- It is supplied complete with standard wall/ceiling brackets
- Fast delivery service: All unit heaters with copper-aluminium heat exchangers and 2-stage, 3-phase motors are available ex-stock.
- Housing self-supporting, completely made of galvanised steel metal, powdercoated on request
- Comprehensive range of modular accessories for simple adaptation to technical and structural requirements (for recirculating air or mixed air operation)
TOP unit heaters can be used for recirculating air and for mixed air operation. They are therefore ideal for the optimum decentralised heating and ventilation of production plants, warehouses and many other buildings in industry and commerce. Special heat exchangers with a low exchange capacity are available for use with low water temperatures.
TOP unit heaters can be combined with a whole range of different models of fans and heat exchangers. Single-phase and three-phase fans are available, with the 3-phase fans also being available as explosion-proof fans. All of the fans are 0-100% controllable.
TOP unit heaters can be selected with the most appropriate heat exchanger, depending on the heating medium being used and the area of use. While copper/aluminium heat exchangers can be operated cost-effectively in areas with normal air pollution, steel heat exchangers should be used anywhere that particularly durable heat exchanger are required or with steam and crossflow heat exchangers for wide temperature spreads.
Yes. If the boiler is overworked, the flow temperature drops until the hear output of the boiler and the output of the units is identical again. This frequently happens in the morning when the units are being heated-up for the first time and the entire building is switching over to day mode.
