Denso Air Conditioning Evaporator Core EVX0990 295 X 248 X 38MM Pad Fittings

The Denso air conditioning evaporator core EVX0990 is an AC component supplied as an individual unit, with a one year warranty. It uses pad inlet and pad outlet fittings and is listed as a plate and fin evaporator type, which is important when matching it to the existing HVAC housing and pipe connections.

Key dimensions for this evaporator core are 295mm long, 248mm high and 38mm deep, with a weight of 2.02kg. Those measurements, along with the pad fitting type, are the main points to confirm before ordering, especially where space in the cab air conditioning assembly is limited.

The identified OEM number is 446600-0990 and the part number is EVX0990. It is described for Komatsu excavator PC300 2001 onwards, and the fitment information supplied also references a wider Komatsu application range, so part number verification is the safest way to confirm the correct replacement.

Application and Buying Notes

Before ordering, compare the EVX0990 part number, the OEM number 446600-0990, and the physical dimensions of 295mm x 248mm x 38mm against the old evaporator core. Pad inlet and pad outlet fittings must match the existing pipe arrangement, otherwise the part may not install correctly even where the model family appears similar.

This evaporator is a plate and fin type unit and weighs 2.02kg. Those details matter when replacing a damaged core because cab air conditioning units are often model-specific in size, connection style and core construction. A match on dimensions alone is not enough if the fitting type differs.

The supplied fitment information points to Komatsu equipment, including PC300 2001 onwards and a broader list of Komatsu machines. That said, model families can vary by serial range and air conditioning configuration, so check the machine identity carefully rather than relying on the model name alone.

If you are cross-checking against a removed part, the clearest identifiers are the Denso brand, EVX0990, and 446600-0990. Where the original label is missing or unreadable, measure the core and inspect the inlet and outlet pads before purchase, as those are the most practical confirmation points for this replacement.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number EVX0990 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

For part number EVX0990, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a air conditioning evaporator core in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include KOMATSU D155AX-6, KOMATSU D155AX-6 2006, KOMATSU D65PX-16, KOMATSU D65PX-16 2011. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Confirm compatibility by matching the EVX0990 part number, OEM number 446600-0990, pad inlet and outlet fittings, and the 295mm x 248mm x 38mm dimensions against the existing unit and machine application.
