Seismic-qualified loop controller

The YS1700 single-loop controller is now fully qualified for seismic and nuclear safety applications. The controller features dual central processing units (CPUs) with automatic failover to provide display and manual control capability if an abnormality occurs in one of the CPUs. Other features include a hard manual backup, battery-free memory backup, and backward compatibility with all previous YS control products. Control applications for the YS1700 in nuclear facilities include feedwater control, feedwater heater, heater-drain control, heat exchanger temperature control, and other flow, level, and pressure applications. — Yokogawa

Console heat pumps

The Envision Series Low Sill Console is a geothermal or water-source heat pump designed for hotel rooms, classrooms, or any room without ductwork. The units' single-speed R-410A rotary compressor is capable of extreme loop-temperature operation. An oversized coaxial heat exchanger with copper inner tube and steel outer tube is designed for maximum heat transfer at normal and low water-flow rates to minimize pressure drop. Additionally, large-face, rifled copper tubes and enhanced corrugated lanced-aluminum fins provide high efficiencies at low face velocities. Available in 0.75- to 1-ton capacities, the console features a compact footprint designed to match legacy consoles for easy retrofitting. — WaterFurnace International

Limescale eliminator

ScaleBlaster is an innovative and environmentally friendly product that eliminates formation of limescale deposits in pipes, cooling towers, and boilers. The integrated circuitry system produces a unique modulating frequency waveform that hits the resonant frequency of calcium molecules, causing them to lose their adhesive properties. Existing scale is removed and never forms again, without the need for chemicals, salt, or maintenance.

Thermal imager

The M12 160×120 Thermal Imager is designed for maintenance and troubleshooting applications. It features a 160-by-120-pixel, high-resolution thermal imager, a visual camera for standard pictures, and a temperature range of 14°F to 662°F. Users are able to capture a thermal and visual image with every trigger pull and toggle between the two with the push of a button. The no-wait display updates the screen image 60 times per second. The unit uses Milwaukee's M12 battery system for quick charging and easy field replacement.
