NEERAJ SHUKLA WHAT IS HVAC ?  AC- AIR CONDITIONING Few People think that HVAC is all about Luxury , Waste of money It is the RIGHT of every individual to live in comfort and HVAC is committed for it. HVAC serves the Industrial Segment to great extent.  AUDITORIUMS & THEATRES  HOTELS AND RESTAURENTS  AND MANY MORE………!! WHAT IS TR ? 1 TR IS AMOUNT OF HEAT TO BE EXTRACTED FROM THE ATMOSPHERE FOR MELTING ONE METRIC TON OF ICE IN ONE TON OF REFRIGERATION (TR) EQUALS TO 12000 BTU/HR.

Duct-mounted VENTUS N-type line is dedicated for easy installation directly in the ducts.

Perfectly suited for buildings, where no mechanical rooms for ventilation devices are present. System equipped with highly efficient energy recovery block based on horizontal cross-flow plate energy recovery. Easy operation and maintenance. See technical parameters Download catalogue VENTUS N-type AHUs are designed foroperation in the most demanding conditions. European quality - 3 year warranty. High performance, no-maintenance direct drive PLUG fans. Rigid and durable casing offered as a standard feature due to the use of advanced Monocoque technology. Monocoque casing desing – even more advanced than frameless solutions used in standard VENTUS Air Handling Units. ECO - cost-saving and environment friendly product Cross-flow heat recuperator - energy recovery system. Cutting edge fan design – airfoil blades with unique trailing edge shape. Installation space savings - compact sizes. Lower installation costs - low device weight.

Fans used in our AHUs  the requirements of ERP 2015 Directive! Rigid and durable casing Ensures of the AHUsthroughout their entire life-cycle which has been confirmed by a EN 1886 conformity certificate. Monocoque technology known from Formula 1 racing and aviation industry ensures excellent mechanical parameters. The X-CUBE CROFCU is a compact ventilation unit that ensures and maintains the essential conditions for all classes of clean rooms. The secondary unit for use with centralised ventilation and air conditioning systems is typically installed in false ceilings. It dissipates high thermal loads and requires only a low fresh air volume flow. The primary air system (patent pending) allows for the direct removal of exhaust air while fresh air is supplied to the room. Suitable for all clean room concepts Pumped chilled water cooling system with room temperature control Increased flexibility if several units are connected Energy-efficient plug fan with EC motor

Addition of fresh air from 50 m3/h to 2000 m3/h Monitoring of filters downstream Control of airlocks for people and material Contamination check by means of pressure zone control Space-saving due to smaller ducts Simple and quick commissioning due to plug and play With the TROX X-CUBE, an air handling unit with unlimited configuration options, TROX sets a new standard in the AHU market and defines considerably higher levels of quality, performance, flexibility, reliability, energy efficiency, and hygiene. Compelling all down the line. TROX now offers everything from a single source: air handling units and components – ideally complementary to each other.For even more energy efficiency and better quality with less coordination effort. For the ventilation of rooms and entire buildings, for filtering, heating, and cooling the air, for heat recovery as well as for humidification and dehumidification, and for volume flow rates of up to 86,000 m³/h
