Unprecedented. Unconventional. Chaotic. Exhausting. Whatever adjective you use to describe them, the first 100 days of the Trump presidency were a crazy time for our nation. People across the country — and around the world — have watched and tried to understand the policy directions of this White House. What have the first 100 days meant for the HVACR industry and what do they portend for the future?
Members of The NEWS’ trainer panel examined compressor valves and determined the best methods for maintaining valves, diagnosing faulty ones, and implementing proper troubleshooting techniques when they go bad.
The NEWS recently sat down with Mark Handzel, vice president, product regulatory affairs, and director, HVAC commercial buildings, Xylem, to discuss the state of the pump industry and what prospective employees should know before they enter the industry.
The Model 700 industrial vertical non-clog waste ejector pump is used for service in industrial wastes, sanitary wastes, process wastes, and rendering wastes. It is designed for long life in tough services with heads to 100 feet total dynamic head (TDH) and flows to 1,500 gallons per minute (gpm).
This recirculation pump incorporates with variable-speed control and built-in control algorithms that can adapt to continuously changing system requirements. Featuring on-demand mode, this pump includes a sensorless demand-based control that allows users to obtain instant hot water when needed.
The Taco 0015e3 is a three-setting, electronically commutated motor (ECM)-powered circulator. With three settings, the 0015e3 is ideal for hydronic systems zoned with circulators or zone valves and provides three maximum-feet-of-head pressure settings to match system requirements — low (5 feet), medium (10 feet), or high (18 feet) with a maximum flow of 16 gallons per minute (gpm).
This commercial modulating Clothes Dryer Duct Booster® (Model CDB8) is designed for indoor installation to increase exhaust flow as high as 1,000 cfm in up to four laundromat capacity clothes dryers.
When replacing a component, it is generally best practice to obtain its replacement by referencing its part number and installing a component with the same part number. Unfortunately, this is not always possible or practical. Due to the nature of the systems we service, many times we are forced to select a replacement component based on either a cross-reference or by matching its specifications to those of the original component.
In a perfect scenario, the oil in a refrigeration or air conditioning system would stay inside the compressor’s crankcase to lubricate the compressor’s moving parts. However, because of ever-changing heat loads on the system and varying system conditions there is no such thing as a perfect system in the real world.
TG Series units are oil-free, variable-speed, magnetic-bearing, and centrifugal compressors. The compressors provide full- and part-load energy efficiency and feature a small footprint, light weight, low vibration, low sound, intelligent controls, and soft-starting characteristics.
