What is supplied
Exact models, variants and the agreed list of included components.
BUYING GUIDE
Understand the arrangement. Define the scope.
Compare separate components, modules, rooftop systems and auxiliary electric cooling before choosing an installation layout.
SYSTEM LAYOUTS
Explore four common starting points.
These diagrams explain common equipment layouts. Use the selected model’s drawings and instructions for wiring, pipework and installation.
Component circuit
Specify the individual compressor, heat exchangers and controls.
- 01Electric compressor
- 02Condenser
- 03Expansion device
- 04Evaporator
Useful where packaging or an existing installation calls for separately selected equipment. Identify every component and its interfaces; one component does not establish the whole system rating.
Module + evaporator
Group the external components, then select the internal arrangement.
- 01Compressor–condenser module
- 02Expansion / connecting circuit
- 03Cabin or equipment evaporator
- 04Matched controls
Match the module and evaporator with their controls, external airflow and connecting circuit. Confirm the exact component versions before ordering.
Rooftop arrangement
Plan around roof space and the scope of the actual assembly.
- 01Roof-mounted assembly
- 02Main power / controls
- 03Cabin air distribution
- 04Other specified components
Check the selected unit’s bill of materials. A rooftop assembly is not automatically a self-contained air conditioner: the RTK range, for example, needs its external-compressor scope identified.
Auxiliary / engine-off
Define how electric equipment works with the intended operating sequence.
- 01Available DC source
- 02Electric compressor / drive
- 03Matched refrigeration circuit
- 04Control and charging strategy
Clarify whether the electric system is independent or integrated with existing equipment. Review oil management and the control arrangement for any shared circuit. Runtime depends on the actual system and available energy.
BEFORE COMMITTING TO A CONFIGURATION
The quotation should make the boundaries clear.
What is installation work
Mounts, routing, connecting parts, wiring and commissioning responsibilities.
What must be verified
The applicable performance conditions, interfaces and released documents.
