environment are covered with grids, in units for outdoor use they can be complemented by
weather-proof blinds.
Valves with a small hole designed for connection of air-conditioning piping are,
as a standard, supplied with an elastic cuff.
The valves are supplied ready for fitting with actuators (actuators may already be
part of the supply) or with manual control. Large valves are split to allow multiple actuators
to operate. Mixing valves can be coupled with a pull rod for one joint control.
Recuperation chamber
The chamber for recovery of heat from exhaust air may be equipped with a rotary
heat exchanger or plate heat exchanger. The heat exchanger consists of a system of
aluminium plates (slats) connected to each other in such a way as to allow for alternate
passage of the exhaust and supplied air between the plates. In winter period, the exhaust
air transfers heat to the aluminium plates, and they then heat the supplied fresh air. The
plate heat exchanger can also
be used for mixing.
Cooling chamber
The cooling chamber is equipped with a Cu/Al plate heat exchanger, where water,
anti-freezing mix or other refrigerant can be the heat transfer medium, according to the
request of the customer. The heat exchanger is equipped with a gradient stainless-steel
condensate drainage pan and a dropper eliminator.
Burners
As a standard, Weishaupt pressure burners burning natural gas, propane-butane,
ELFO (extra light fuel oils) and other types of fuel are supplied with the unit. Burners are
supplied, as a standard, with two-stage or modulation regulation. Burners include complete
gas fittings, electrical controls and all safety features.
Electrical equipment of the units and MaR
The units can be supplied with control and protection elements in any range
according to the request of the customer. The units can be supplied, for example, only with
fitted actuators, can be supplied incl. basic control cabinet only to protect and start up the
main engines.
Regulation supplied with the unit is designed for particular action, e.g. in terms of
regulation requirements on room temperature (halls) or inlet temperature (e.g. paint
boxes).
Unit control can be manual (a combination of basic electrical control and manual
valve control), manually electronically from a security cabinet or through advanced
regulators with a link to other control systems.
