High-efficiency furnace motor Rescue EcoTech® dramatically upgrades the electrical efficiency of a furnace while lowering operating costs and improving comfort. Through its patented design, an ECM motor connects directly to the furnace board in just the same way as the existing PSC motor it is replacing.
The Eon 42 variable-speed, constant-torque motor is designed for direct-drive blower applications such as fan coils, kitchen ventilators, air curtains, and unit heaters/coolers. According to the manufacturer, the motor saves up to 56 percent of the electricity consumed by the motor.
Designed for HVAC applications, Climatherm® SDR 17.6 is now available in large pipe sizes up to 24 inches in diameter. SDR, or standard dimension ratio, is the ratio of pipe-diameter-to-wall-thickness, and these larger pipe offerings have reduced SDRs in order to keep weight and costs down.
With a zinc-plated steel housing and finishing, the FireBag® thermal-activated gas shut-off device automatically turns off the gas supply in the event of a fire, preventing explosions and the spreading of fire.
A heavy hurricane and tropical storm season may bring more corrosion damage to HVACR systems than we normally see. Now, as many contractors start to clean up systems, and others are scheduling preventive maintenance customers, coil care and corrosion prevention should be high on the work list.
