Unit description

Transportation and packaging 

In cooling mode, the unit (an 
air-cooled chiller) takes heat out 
of the operating medium to be 
cooled, water or a mixture of 
water and glycol, within a closed 
medium cycle in the evaporator 
(plate heat exchanger) and passes 
it on to the closed cooling cycle. 
As a consequence of the heat 
exchange, the medium cools and 
the refrigerant in the cooling cycle 
vaporises under low pressure. 
The gaseous refrigerant 
enters an electric compressor 
(scroll construction) which 
increases the pressure and 
the temperature of the refrigerant. 
The gaseous refrigerant is 
led into a finned condenser, 
which, as a consequence of 
the heat exchange, condenses 
the refrigerant under high 
pressure to a liquid. The air 
emerging at the condenser heats 
the environment. The liquid 
refrigerant is fed by means of a 
variable injector valve back to 
the evaporator where the circuit 
begins again.
A return temperature dependent, 
seamless controller, which ensures 
the unit's operation and all of 

Intended use

Depending on the model and 
the unit, the units are only 
intended to be used as a chiller 
for the cooling of the operating 
medium water or a water-glycol 
mixture within a closed medium 
cycle.
Any other use or use in a way 
that exceeds the definition above 
is considered non-intended 
use. The manufacturer/supplier 
assumes no liability for damages 
arising from non-intended use. 
The user bears the sole risk in such 
cases.
Intended use also includes working 
in accordance with the operating 
and installation instructions and 
complying with the maintenance 
requirements.

Applicability

Within the course of continuous 
further development of all 
products, REMKO GmbH & Co. 
KG reserve the right to carry 
out technical changes to the 
units as well as updates to 
the documentation. 
The documentation on the unit 
(name plates, wiring diagrams, 
etc.) shall be considered as part of 
the overall documentation. 

Ecological design directive

The regulation (EU) 2016/2281 
(LOT 21) approved by 
the European Commission is 
the enforcement action for 
the ecological design directive 
2009/125/EC, whose principal 
objective is to reduce the primary 
energy demand in the European 
Union by 2030 and to reduce 
the emissions of hazardous 
substances associated with this.

The chillers from REMKO 
comply with the applicable 
energy requirements from 
the ecological design directive. 
The product datasheet required 
per the ordinance, to verify 
ERP conformity is attached as 
a separate document and is also 
available for download from 
www.remko.de.

Proper handling

Insofar as intervention is required 
in the refrigerant circuit of the unit 
during maintenance or repair 
work, all work shall be carried 
out exclusively by persons and 
companies who have a certificate in 
accordance with the prerequisites 
of EC ordinance no. 517/2014 of 
the European Council.
