In recent months, Tecumseh Products Co. has made a number of announcements related to a line of refrigeration compressors that are optimized for HC refrigerants, an expansion of its line of large frame rotary compressors, and the introduction of direct current (dc) compressors.
For patching holes in copper and aluminum tubing, Patch Rite high-pressure patching system is simple to apply. According to the manufacturer, the key to the bonding strength of the patching system is the 0.020-inch cavity in the patch.
Expandable from 1 to 3 feet or 2 to 5 feet, a single-wall expandable-flexible gas vent connector has been specifically designed with the contractor in mind, says the company. Model EFC creates a remarkably simple connection between the appliance and the manufacturer’s Type B gas vent.
Designed for high-efficiency heat pump and air conditioning systems, the new Copeland Scroll® variable-speed compressor allows heat pumps to achieve 13 HSPF, 20-plus SEER efficiency, and 40 percent greater year-round energy savings than standard heat pumps, says the company.
The Wags (water and gas shutoff) valve is a simple, inexpensive, and reliable way to guard against disastrous water problems that can arise when water heaters develop a leak. The valve, which can be used for new or existing water heaters, is totally mechanical and can be installed with or without an electric harness.
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.
