Partnering opportunity

Preheater of cold air before heat pumps and ventilation systems


The SME from Kyiv (Ukraine) offers an air-heater for reducing the energy consumption in ventilation systems and increasing the coefficient of transformation heat pump (HP) of air-air or air-water type at temperatures below minus 5 °C using the heat of crystallization of water. Installed power of HP is reduced. The organization is looking for partners to implement this offer in the form of a commercial agreement with technical assistance or technical cooperation agreement.

Partner sought

Engineering organizations - for the purpose of joint designing in the form of technical cooperation agreement, representatives of manufacturers of heat pumps of air-air, air-to-water types, manufacturers of ventilation equipment and communal organizations - for the implementation in the form of a commercial agreement with technical assistance.


The organization is creating (since 1993) the means and systems of automation, as well as developing integrated projects using renewable energy sources for the modernization of municipal energy power engineering, has a skilled staff and expertise to design and create effective heaters as elements of power systems. In the northern countries of Europe, Asia and America, the amount of frosty days is from 70 to 200 per year. Such conditions in winter make it possible to heat the air before the evaporator of the heat pump (HP) to -3 – 0 ºС. This increases the coefficient of transformation (COP) by 25-35%. At the same time HP can work at temperatures -20 – -50ºС. The developed technology also provides up to 50% energy savings for ventilation in winter and is especially advantageous for rooms with a large ventilation rate. With simultaneous application of this technology for HP (before the evaporator) and for ventilation systems (in front of the air coolers) in frosts, up to 60% of energy can be saved. Due to the high heat of crystallization (334 kJ / kg), the water consumption is insignificant. The resulting ice can be accumulated for summer cooling (storage of products, air conditioning, cooling of data centre rooms). The organization is looking for partners - SMEs working in the field of heat supply for industrial enterprises and utilities sectors to participate in the joint design and production of new air heaters. The preferred form of cooperation is a commercial agreement with technical assistance or technical cooperation agreement.

Advantages and innovations

This technology leads to: - reduction of installed capacity and power consumption in HP and traditional preheaters of ventilation systems, - allows HP operate in frosts without the use of expensive ground heat exchangers, - decrease investment, - decrease of CO2 emissions into the atmosphere. The technology is ecologically absolutely clean.

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
