Integration & documents
Installation drawing
Use the drawing for the exact HETA-T model in the technical specification. Confirm the current outline, cabinet cutout and wiring before manufacture.
Scope of supply
Confirm the scope of supply with your quotation. The cooler, DC power supply and temperature controller should be specified separately; photographs alone do not establish which accessories are included.
Installation planning
Plan the cabinet opening
Obtain the outline, mounting cutout and wiring drawing for the exact model. Check available space on both sides of the enclosure before installation.
Keep the heat path clear
Follow the approved installation instructions for airflow and hot-side heat rejection. Confirm orientation and clearance for the cabinet layout.
Specify the complete assembly
Match the DC supply and controller to the selected cooler and application. Confirm wiring, accessories and the scope of supply in the quotation.

Include the model, quantity, maximum ambient temperature, target internal temperature and estimated heat load. Add available DC supply and cabinet dimensions if known.
Application questions
Is cooling capacity the same as power consumption?
No. Cooling capacity describes heat removed from the enclosure; power consumption is electrical input. Select with both values and confirm performance at the actual operating temperatures.
How do HETA-T, HETA-TS and HETA-TP differ?
T is the standard through-wall configuration. TS and TP use different fan positions relative to their stainless-steel protective covers. TP places both cold-side and hot-side fans inside the covers for greater mechanical protection. Select the exact construction and check its specifications; a protective cover is not an IP-rating guarantee.
Are a power supply and temperature controller included?
The scope of supply is confirmed in the quotation. Specify the cooler, power supply and controller requirements separately when requesting a complete assembly.
What information is needed to select a model?
Provide the maximum ambient temperature, target enclosure temperature, estimated heat load, available DC supply and cabinet dimensions. Include the quantity and any space or installation constraints.
Can an ETC80 controller be used with this cooler?
The ETC80 family may be considered as an optional controller. Confirm the exact controller variant, voltage, output capability, wiring and supply scope for the selected cooler. A family reference does not establish compatibility or inclusion.
