Heat pumps transfer heat rather than generating it by burning fuel. In suitable commercial and industrial applications, they can provide heating and cooling while reducing the use of on-site fossil fuels. The right choice depends on the building, required temperatures, available electrical capacity and operating costs. How heat pumps work A refrigerant circuit moves heat […]
In this case study Project background System changes Reported outcome Planning questions Related services Boiler plant retrofit: project background At one of our customer’s locations, Arvin Air Systems identified an opportunity to retrofit the boiler plant, comprised of four atmospheric boilers, with 83% fuel efficiency and intermittent pumping, to a highly efficient boiler plant – […]
In this article Local exhaust systems capture contaminants near the source Hoods, ducts, air cleaning and fans work together Compare capture performance and operating costs Include make-up air in the assessment Three checks for a local exhaust assessment Local exhaust systems capture contaminants near the source In most industrial plants, hazardous or nuisance contaminants are […]
HVAC equipment inspections help facility teams investigate cooling problems and plan appropriate repairs. Start with the operating symptoms and maintenance history rather than assuming which part has failed. During the service life of HVAC equipment, certain parts may require replacing. Identifying these problems and having the repairs completed can help support reliable operation and identify […]

Summer plant temperatures can affect comfort and contribute to occupational heat stress. Engineering changes can help reduce exposure, but they do not replace a workplace heat-stress assessment, appropriate rest breaks, hydration, acclimatization or emergency procedures. Contain the heat source The first step is to contain, as much as possible, the heat source with effective use […]

Relative humidity (RH) is the ratio of amount of water vapour present in air, to the greatest amount possible at a given temperature. A RH of 30% indicates that at the current temperature, the air is only holding 30% of the moisture it could. Failing to maintain ideal levels of RH can cause health problems, […]

COVID-19 mitigation in buildings includes attention to ventilation, air cleaning and maintenance within a wider prevention approach. The following HVAC guidance explains the limits as well as the practical checks. Ventilation and air cleaning can help reduce airborne respiratory particles indoors. They do not eliminate infection risk or replace current public-health advice. This article updates […]
To repair vs replace HVAC equipment is a decision about condition, risk and the scope of work, not age or purchase price alone. Use the following checks to frame a site-specific assessment. Deciding whether to repair or replace HVAC equipment is never easy; however, the following factors can help you make a decision: Reliability in […]
The forgotten solution: maintaining HVAC controls Forward thinking and creative Professionals are engineering solutions to mitigate global warming and climate change. In the heating, cooling and ventilation sector many Professionals are implementing the use of high efficiency boilers, air conditioners, fans, pumps, variable speed drives, and constructing energy-efficient energy neutral buildings. Automated controls and remote […]
