We take care of your air.
Backed by decades of experience in designing and manufacturing HVAC equipment, our air handling units deliver air conditioning, ventilation and air distribution — from restaurants to pharmaceutical plants.

Air handling unit division
Versatile air handling units with outstanding performance.
Drawing on decades of experience in manufacturing and designing HVAC equipment, our air handling unit range is engineered to solve air conditioning, ventilation and air distribution challenges.
Our air handling units cover airflows from 800 to 100,000 m³/h. They are built in more than 30 standard sizes with extensive scope for optimisation, always tailored to client requirements and project specifics. References include Hotel Gorski, Serum Institute of India, SC Big Novi Sad and many others.
Ventilation
Heating, cooling, filtration and heat recovery in a single modular casing.
Hygiene
GMP, FDA and HACCP designs for operating theatres, laboratories and pharma.
Swimming pools
Dehumidification and energy recovery for pools — from private to Olympic.
Energy
Up to 80% heat recovery with a two-stage plate heat exchanger.
Product range
Four models. The right unit for every project.
Choose a model and look inside — casing, sections, airflows and applications.

std | pro
The standard TERMOVENT air handling unit for a wide range of applications — from cafés and restaurants to hotels, shopping centres and public buildings, through to industrial plants, warehouses and production halls.
Its modular design supports a broad spectrum of applications by combining functional units (modules) for ventilation, heating, cooling, filtration, humidification, dehumidification, heat recovery and energy regeneration.
- Casing of aluminium profiles and powder-coated panels, with polyurethane or stone wool infill
- Thermally broken modular design — assembled on site
- Outdoor or indoor installation

hydra | pro
Climate control for all types of indoor swimming pools — from private to Olympic. This stand-alone solution maintains indoor conditions while making maximum use of the energy in the exhaust air, which can also be used to heat the pool water.
The focus is on major energy savings and economical operation throughout the unit's service life. Two models: hydra | pro and hydra | pro Compact.
- Double plate heat exchanger; Genius models with an integrated heat pump
- Plug-and-play unit with EPOXY-coated interior
- Available with polypropylene heat exchangers

hygiene | pro
A special version of our modular units for demanding projects that require a defined air cleanliness class in line with GMP, FDA and HACCP — operating theatres, laboratories, pharmaceutical plants, and the food, defence and electronics industries.
- Compliant with GMP, FDA and HACCP standards
- Prevents contamination and the growth of unwanted microorganisms
- Easily accessible components for cleaning and disinfection
- Used in operating theatres, laboratories and pharma

energy | pro
Two families of units — energy | pro and energy | pro Adiabatic. Sensible heat is transferred between the exhaust and fresh air streams by a two-stage plate heat exchanger, with heat recovery efficiency of up to 80%.
These energy-efficient air handling units maintain optimal indoor conditions fully autonomously.
- Supplied complete with control cabinet and automation
- Prevents condensate formation and water leakage into the exchanger section
- Eco-friendly system with lower power consumption and low CO₂ emissions
- Also available without integrated compressor-based cooling, on request
Anatomy of an air handling unit
The path of air through a std | pro unit.
Scroll to follow the air from the outdoor louvre to the room — five sections, one modular unit.
Dampers and pre-filter
Motorised dampers regulate the fresh air intake, while the pre-filter captures coarse particles and protects every section downstream.
Plate heat exchanger
Heat from the extract air is transferred to the fresh air without mixing the streams — up to 80% heat recovery.
EC fans
Energy-efficient fans with EC motors adjust their speed to the building's actual demand.
Heating and cooling coils
Copper-aluminium coils bring the air to the set temperature, with humidification or dehumidification where required.
Final filtration
Fine filtration before the air enters the room — and H13/H14 HEPA filters for clean rooms and operating theatres.
How heat recovery works
Heat you would throw away — returned to the building.
In the energy | pro two-stage plate heat exchanger, the extract air passes its heat to the fresh air without the streams mixing. In winter, at −5 °C outside, fresh air enters the room pre-warmed to around +17 °C — before the heater even switches on.
