PLATE HEAT EXCHANGERS

Crossflow plate heat exchanger

The crossflow plate heat exchanger is an energy recovery system consisting of an exchanger package and housing, suitable for heat recovery in winter and cold recovery in summer. The exchanger package consists of aluminium or stainless steel plates with V-shaped spacers and flow technical optimised profiles. The air flows cross each other at right angles, so there is almost no transfer of moisture or odours. The plate heat exchangers are temperature-resistant, in the silicone-free standard version up to 90°C and in the special version with silicone-containing seals up to 200°C.

Counterflow plate heat exchanger

The counterflow plate heat exchanger is an extended version of the crossflow plate heat exchanger for heat exchange. Here too, the air flows from the air outlet and the outside air are completely separated and guided past each other on thin and parallel fins. Due to the extended, horizontal flow path through the inside of the cross-flow heat exchanger, a counterflow is created in addition to the cross-flow for an even higher heat recovery coefficient.

The counterflow heat exchanger can be made of aluminium, aluminium with anti-corrosion coating and plastic.

Rotary heat exchanger

The rotary heat exchanger is a regenerative energy recovery system in the form of a rotor with a rotating, honeycombed storage mass. The system is driven by a motor/reducer. The recovered power can be controlled by adjusting the rotation speed.

Condensation rotor: high-quality aluminium foil heat exchangers to recover heat or cold from ambient air.

Enthalpy rotor: these heat exchangers have a hygroscopic surface that improves moisture transfer.

Adsorption rotor: heat exchangers with a highly hygroscopic zeolite coating that ensures maximum temperature transfer and humidity throughout the year. In hot and humid regions, for example, these rotors provide immense energy savings for air conditioning.

The casing can be supplied in galvanised steel, stainless steel or aluminium.
Optional: special epoxy coating for aggressive or corrosive conditions.

KV system (Twin-coil)

The KV system is a regenerative energy recovery system with one or more combined heat exchangers in the supply air and return air. The advantage of this energy recovery system is that the airflows are completely physically separated from each other. This makes this form of energy recovery extremely suitable for applications where, for hygiene reasons, no leakage or cross-contamination between the airflows is permissible.

Adding the hydraulic module HPS, including the intelligent control unit IMPERIA 51 HPS, creates a highly efficient overall system.
The overall efficiency of the system can be further increased by adding other options, e.g. integration of secondary energy.
