The Parallel Sensorless Pump Controller is an add-on control device that coordinates the output of multiple pumping units in a parallel configuration to achieve significant energy savings.
Available in three sizes, with three speed settings per pump, the AquaPUMP™ hydronic circulating pump has a twist-to-fit flange which rotates 90 degrees to fit every application, the company said. The built-in hardened ceramic internal shaft and bearings offer high-corrosion resistance and longer performance.
The Design Envelope IVS Twin Vertical in-line pump for commercial HVAC systems combines two variable-speed rotating assemblies in one shared casing. The twin-pump design is a variable-speed, duty/standby solution for any application that demands constant availability, energy savings, and a small footprint.
Robur’s absorption process combines the advantages of a condensing boiler and an electric heat pump into one unit. The air-to-water reversible heat pump supplies hot water up to 140°F or chilled water down to 38°F.
Minimizing wear on HVAC equipment and maximizing system uptime is the VLT® HVAC Basic drive. It is a robust variable-speed drive solution that delivers highly reliable HVAC performance for basic fan and pump operations, the company said.
With a working pressure of 175 psi, the Viridian line of wet-rotor pumps with an ECM motor offers an 80 percent decrease in energy consumption compared to a standard commercial pump of the same size, says the company.
Instant water heaters, high-tech boilers, and steam solutions are just a few examples of wet heat technology. Here are a few products in that segment that might be of interest to the HVACR contractor.
HVAC contractors have many choices of hydronic heating equipment, and these are a few examples of how knowledge of wet heat technology can make the selling job a little easier.
Taco’s Viridian pump line makes its first appearance at the 2012 AHR Expo in Chicago. The wet-rotor pump with an ECM motor offers an 80 percent decrease in energy consumption compared to a standard commercial pump of the same size, the company says.
