Tenders

No. 1 · October 2026

For municipalities, regions and other public building owners.

Built for public tenders

Public building owners buy through tenders and consultants, and the documentation is half the job.

We supply the manufacturers’ data sheets, sound data and certificates, so the consultant can write the solution into the tender material.

Heating and cooling. Swimming pools and ice rinks need both heating and cooling. Oilon ChillHeat handles both and recovers the surplus heat.

From the school to the hospital. iDM AERO ALM 10-50 MAX modulates steplessly between 10 and 50 kW, and iDM’s complete MAX range goes up to 1,500 kW in cascade. Oilon ChillHeat covers approx. 30–450 kW per unit and up to approx. 120 °C.

Temporary heat. Kroll MW40 and MW80 are mobile air-to-air heat pumps that heat building sites, halls and tents down to −20 °C outdoor temperature. The heat is delivered through hoses, and the unit regulates itself to the set temperature.
