Air handling unit is only as good as its construction. Leaky casings waste energy, weak fans create noise and vibration, and cramped internal layouts make maintenance painful. VENTTK designed its modular AHUs to solve these problems at the source — combining recognized manufacturing standards with engineering choices that pay off over the life of the equipment.

Standards and Materials That Back Every Unit

Every VENTTK AHU complies with EU harmonised standards EN 1886 and EN 13053, meeting CE requirements including Machinery, LVD, EMC and Ecodesign (EU 1253/2014). It is produced under ISO9001 and ISO14001 qualified processes. The units use carefully selected materials, with main components sourced from top Chinese brands or imported suppliers, so reliability is built in from day one.

A Casing Engineered for Tightness

The most important engineering decision in an AHU is the casing. VENTTK units use a modular, double skin sandwich construction — 0.5mm galvanized internal and external panels with 30mm polystyrene insulation at a minimum density of 45kg/m³. A unique no cold bridge design, combined with airtight sealing between casing and frame, keeps total air leakage at or below 2.5%, protecting insulation performance and reducing energy loss. The modular design also makes sections interchangeable, so installation, transport and maintenance stay simple throughout the unit's service life.

Performance and Serviceability, Together

Inside the casing, dynamic balanced double inlet centrifugal fans deliver high efficiency, low vibration and low noise, while high efficiency heat exchanger coils ensure reliable cooling capacity — with optional breakwater panels and coil water carryover kept at or below 3×10⁻⁴ kg/kg. The internal layout leaves proper space for maintenance and cleaning, and the durable, permanently finished structure keeps the unit looking good while protecting your investment.

One Platform, Many Applications

Because each module can operate independently or work together with fan coil units for fresh air delivery, VENTTK AHUs cut operating costs and energy use while improving indoor air quality. They are used across mechanical, electronic, textile, medical, chemical, energy and food industries, and are an ideal fit for restaurants, office buildings, hospitals, theaters, supermarkets and sports facilities.
