I am interested in locating heat-pump manufacturers, around the world, who would be able to design, fabricate & supply heat-pumps in line with the following broad specification:

1. Output heating power : 500 kW
2. Heating source - air, water - temperatures still tbc
3. Skid-mounted solutions would be of interest
4. Final destination : S.E. Asian country
5. Delivery temperature : water delivery as high as possible
6. If output power of 500kW is too high, then modular solutions of lesser output power would be considered.
7. CO2, HFC, or suitable alternative refrigerant solutions are of interest.

The final specification is scheduled to be firmed up within the next 2-3 month time-frame, upon a detailed site review.
