with a slope in the direction of condensate drain, made of stainless steel V4A
powder coated, including drain tray, conform with VDI 6022
– Air-cooled condenser according to VDI 6022: heat exchanger as Cu/Alu model for
R 407c refrigerant, fins made of aluminium, frame elements made of AlMg3, pipes
made of oxygen-free copper
– Compressor unit: refrigeration circuit with a fully hermetic scroll compressor
– with optimized heat exchanger combination for maximum COP values, mounted on
anti-vibration mounts, circuit includes filter drier, liquid collector, thermostatic
expansion valve with MOP and external pressure equalisation, all necessary
shut-off valves, monitoring and safety devices (pressostat, icing sensor, etc.)
Droplet eliminator – made of plastic with an aluminium frame at air velocities on supply and exhaust side
exceeding 2,5 m/s is necessary
Fan unit:
GEA centrifugal fan „LESS ENERGY SYSTEM“
– Optimized operating point, double side suction, coated surface model
– Three phase motor, protection class IP55 , model type B3, complete belt drive, easy
service thanks to one bolt tensioning sled
– Fan/motor unit mounted on anti-vibration mounts
Air damper system: – Dampers with sealing lips, leakage volume flow 20 m 3 /h m2 (dp=100 Pa), for circulating
air/bypass, for fresh and exhaust air. Circulating and fresh air rate 0-100%
– Coated Almg3 damper blades with flow efficient profile, operate in opposite directions.
Driven by double sided, anti-static plastic gears PA6 as fiberglass reinforced
model (resistant to chemicals) including special actuator for each damper
– Control of the individual actuators using continuous DDC signals
Filter for fresh and
exhaust air:
– Filter units conform with VDI 6022
– including bag filter as of DIN/EN 779, synthetic fiber filter medium
– All filters are fitted with a differential pressure switch for filter monitoring via the DDC
Heat recovery system:
GEA „ECOPLAT POWER PLATE“
– symmetric high performance plate heat exchangers, recuperative heat recovery by
using two cross-flow aluminium plate heat exchangers (corrosion protected Al99
with best temperature coefficient). Surface is additionally coated with thermoplastic
material. Largest possible heat exchange surface using entire unit depth with minimum
pressure losses. Optimal selection with consideration of operation conditions.
Best efficiency rates within entire outdoor temperature range, especially resistant to
corrosion and wear. Swimming pool configuration.
