Building Automation

75F HyperStat Split

The 75F HyperStat Split is a control that enables contractors to upgrade roof top units (RTUs) with ease. Using only two existing wires from the RTU to the thermostat, the company’s HyperStat Split provides dual enthalpy economizer, demand-control ventilation, and VFD control. The device tracks occupancy, temperature, VOC, CO2, humidity, light, sound, and optional particulate matter measurements every 60 seconds for integration into a built-in analytics package. Two standout features includes the device’s ability to work with the existing two wires provided for a standard temperature sensor while still delivering advanced control sequences showing that the hardware can work with existing infrastructure without excessive complexity, and the device’s eight onboard sensors and native cloud connectivity for real-time analytics prove that demand for indoor air quality management can be met in a modern and user-centric manner.


The DSG compressor from Danfoss is designed for low pressure refrigerants such as R1234ze with low global warming potential (GWP). These refrigerants would usually require a much larger compressor size to have the same capacity as high pressure (R410A, etc.) refrigerants. Applications for the compressor include chiller systems, with a wide range of compressor capacities available to support unit design requirements. As chiller manufacturers need to transition to lower GWP refrigerants they will need to move to medium and low-density refrigerants, and the DSG will enable a smooth transition without a significant increase in physical compressor size. It is qualified for R1234ze which is a replacement for the market that has been dominated by R134a. The DSG can also be used with other refrigerants with similar properties.


Ephoca‘s Nextac introduces a new generation of packaged terminal air conditioner (PTAC) units with improved comfort control. The unit’s features include R32 refrigerant, twin rotary inverter compressor, heat pump performance to -10F (-23C), integrated ERV, MERV13, zero air leakage, self-cleaning coils, 27 dB(A) operation, in an all-metal paintable cabinet. No drain is required for cooling or heating. Often considered a “cheap, low-end” product, installers have favoured PTACs for their affordability and ease of installation. However, those living with PTACs in their homes have endured poor performance with no better options to fit existing sleeves. Nextac aims to disrupt this status quo with this new high-efficiency and quality PTAC by compelling manufacturers to enhance their PTAC lineup, making them more efficient, aesthetically pleasing and adding more insulation for quieter operation and a better seal.

Indoor Air Quality

It provides data beneficial for achieving various sustainability certifications (LEED, WELL). WellStat is completely integrated, customizable and provides a single, unified enterprise hardware, software, and mobile platform experience. With WellStat, customers can optimize their existing asset’s performance while promoting a safer and healthier work environment. Additionally, WellStat uses the highest caliber sensors available and maintains accuracy through persistent, over-the-air calibration that never requires maintenance. Monitoring systems are tested, calibrated and always accurate, all the time including 14+ IAQ sensors monitoring: temperature, relative humidity, particulate matter, carbon dioxide, ozone, total volatile organic compounds, formaldehyde, reset TVOC, dew point, wet bulb, light level, carbon monoxide, occupancy, pressure, sound DB, and duct flow.


Rheem Water Heating‘s Triton Light Duty (50- and 75-gallon) water heater is a solution for small businesses. The Triton Light Duty is an intelligent high efficiency commercial gas water heater with built-in smart monitoring and leak detection, the unit prevents downtime, and manages water heater issues. Its patented combustion system and helical coil heat exchanger provide maximum thermal efficiency and durability. The latest Triton offers up to 97% thermal efficiency and eliminates downtime with the ability to detect and prevent water heater problems before they occur thanks to LeakGuard — an all-inclusive leak detection and prevention system capable of limiting water leakage outside the tank. With porcelain/ glass-coated steel, corrosion is minimized, extending the life of the tank while its minimum weld joint construction increases durability. The unit features a built-in condensate neutralizer, which eliminates the need for a separate device to raise the pH of the condensate for safe draining.


The AirGreen -BMIL brine-based DX refrigerant system essentially creates a low dewpoint “heat pump” for cold room applications – providing <26F dewpoint supply air in a single process step. Because of its simplicity, this packaged unit design provides up to 50% energy savings while also reducing capital costs. Solid desiccant products can only achieve supply air at 55F with a 40-45F dew point, and to lower the dry bulb temperature to as low as 33F it requires three or more pieces of equipment at considerable capital and energy penalty. The unique low temperature brine solution achieves this performance because it simultaneously cools and dehumidifies. For customers, it also eliminates the downtime related to multiple defrost cycles, or worse, downtime for cleaning if condensation forms. Further, the AirGreen product only needs low regeneration temperatures (110F), compared to solid desiccants requiring 180F or more. This low temperature hybrid brine system is uniquely suited for cold storage applications and addresses a $5.1B market.
