Air-cooled chillers

Air-cooled chillers

LC Series air-cooled chillers are designed to provide consistent leaving-water temperature with part-load efficiency in a compact package. Features include 10- to 100-percent modulating capacity, R-410A scroll compressors, factory-installed pumping packages, low-ambient options, shell-and-tube or brazed-plate heat exchangers, and capacities from 5 to 54 tons. Factory-assembled, piped, and wired to accept a single-point electrical connection, the chillers include access doors in areas subject to scheduled maintenance. Laminated unit-specific color-coded wiring diagrams in point-to-point and ladder form are permanently affixed inside of the control compartment. Housed inside of the compartment and protected from weather and outdoor elements are microprocessor controls compatible with BACnet, Modbus, Johnson N2, LonTalk, and Automated Logic protocols. Low-ambient control on all of the refrigeration circuits allows mechanical cooling at decreased ambient temperatures.

Video smoke-detection systems

Video smoke-detection systems

Video smoke-detection systems are based on the computer analysis of video images provided by closed-circuit-television cameras (bl a ck- andwhite, color, infrared, existing, or new). The systems use sophisticated software algorithms to identify the motion pattern of smoke and fire while ignoring other on-screen movement patterns on up to four cameras simultaneously.

Supply sticks

Supply sticks

Series PCWS pressure-regulating supply sticks eliminate connections and minimize space requirements in plastic piping systems by combining a number of valves, connectors, and gauges into a single-piece design. The reduction in size and connections increases piping strength by 1,400 percent.

Pipe-freezing units

Pipe-freezing units

SF-2500 SuperFreeze pipe-freezing units isolate sections of copper or steel pipe with ice plugs, eliminating complete system shutdowns and draining. The units can form ice plugs in as little as 5 min in steel pipes with diameters of up to 2 in. and copper tubing with diameters of up to 2½ in. One or two plugs can be formed with a single unit at the same time. Flexible rubber hoses connect freeze heads to the units.
