TANGRA presented the new series of frequency inverters TANGRA FI

The frequency inverters are increasingly used in ventilation, air conditioning and heating. According to international studies, between 65% and 70% of electricity is consumed by building asynchroned drives on fans and pumps with constant speed.
The design of systems for ventilation, air conditioning and heating is based on the maximum occupancy of the buildings. In everyday life,
the maximum occupancy is reached in very rare cases. The use of frequency inverters allow smooth regulation of ventilation and heating systems.

Air handling units TANGRA AHU  – guarantee for the air quality!

Modern buildings are better and better thermally insulated and the joinery (of the windows and doors) – more and more tightly closed.

Naturally the association with a thermos arises where the coffee is hot and aromatic, even after 12 hours. The only disadvantage is that we live in this thermos!

People in industrialized countries spend between 70 % and 90 % of their lives in closed premises. The lack of sufficient quantity fresh air leads to reduced working capacity, increase in allergies and diseases, especially of children and young people.

There is a solution – healthy, energy-saving and environmental!

Air handling units of TANGRA are designed to meet the needs of ventilation, heating, cooling and energy recuperation of various types and purposes public and industrial buildings. All ventilation and air conditioning units are designed on a modular basis, which facilitates their transportation and installation.

Analysis of the possibilities for energy recovery through recuperation in the ventilation and air conditioning systems.

It seems the discussion for the necessity of energy recovery systems is over not only in Western and Northern European countries, but also in Bulgaria. For the people who made serious effort for convincing and proposing legislative changes in the last 20 years, it is a real success. Today it is rare to see a ventilation or air conditioning project without energy recovery (recuperation or regeneration).

The economic pressure (rise of energy prices) surpassed the legal regulations. Designers and investors reacted more adequately than the legislators.

The next important step is the choice of the right energy recovery system. The right choice means a cost-effective choice that doesn’t compromise the microclimate.
