We engineer industrial ventilation systems that integrate seamlessly into your facility and provide healthy clean air to workers and operatives, along with many other benefits of a clean air environment. Engineered Temperature Solutions can design, supply, install, maintain, and balance your make-up air & exhaust system. 

Preventative Maintenance

Maintain efficiency & save on energy costs. Avoid an expensive repair or unexpected replacement by getting year-round protection with a preventative maintenance care plan for your heating & cooling system.


For optimal comfort and energy efficiency, the exhaust and make-up systems must be well-balanced to provide stable building interior pressure. A building with a poorly balanced ventilation system will experience either an accumulation or reduction in internal gauge pressure, both of which are undesirable. 


It is of critical importance that where required, a DOAS is carefully designed and installed to achieve the desired room and overall building pressure balance. ETS will make sure that your industrial ventilation system is seamlessly integrated into your building.

An HVAC exhaust system is a ventilation system that removes contaminated air from a building or space and exhausts it outside. The system may include ductwork, grilles, and dampers to direct and control the airflow.

Spaces that may require an HVAC exhaust system include kitchens, bathrooms, laboratories, medical facilities, and manufacturing plants. : An HVAC exhaust system can help maintain indoor air quality, remove harmful pollutants and odors, and prevent the spread of airborne illnesses.

Regular maintenance is important for ensuring the proper operation and longevity of an HVAC exhaust system. This includes cleaning the ductwork, checking the fans and motors, and inspecting the system for leaks or other issues. The efficiency of an HVAC exhaust system can be improved by optimizing the air and exhaust flow, using energy-efficient fans and motors, and ensuring proper maintenance and operation of the system.

Yes, HVAC exhaust systems can be integrated with building automation systems, allowing for centralized control and monitoring of the system.

Keep Proper Pressure

​Operating a building at an excessively negative pressure condition can, in some instances, create poor environmental conditions due to one or more of the following: - Inefficient exhaust system operation due to excessive static pressure resistance being presented to the fan. - Poor room temperature uniformity (cold at low level, warm at high level), potentially leading to higher heating system operational costs. - Difficulties with opening or closing doors between vestibules. - Contamination and pollutants being introduced from the external environment or adjacent building spaces. It is therefore of critical importance that where required, a DOAS is carefully designed and installed to achieve the desired room and overall building pressure balance.

Additional Information

​For buildings which operate exhaust systems, whether they be for the purposes of general room extract, process extract or dust/fume extract, dedicated outside air system is typically installed to maintain a satisfactory room or building pressure balance. The desired pressure will be dependent on the application. For example, a cleanroom facility will typically require to be maintained at a positive pressure condition to minimize contamination from the external environment. An industrial kitchen area will require to be kept at a negative pressure condition to prevent the potential spread of odors and cooking oil vapors/smoke spreading to adjacent restaurants or cafeteria areas. This does however not preclude the requirement for a DOAS unit, as in this example, large extraction rates are typical and make-up air must be introduced at (or usually close to) the same rate that contaminated air is exhausted.
