Evapco Closed Circuit Cooler

Evapco has developed a unique method of wrapping the elliptical tubes used in their coil products with a spiral fin. This development raises the dry-bulb switchover temperature, improving the dry operation of closed circuit fluid coolers. Self contained control strategies have been developed to minimize water usage. We see many potential applications for these coolers in heat pump projects, process cooling, and data center applications.

ClimateMaster TE series HPs

ClimateMaster, Inc. announces the launch of its new Tranquility® 30 Digital (TE) Series heat pump unit with high-efficiency two-stage operation to accommodate a wide variety of commercial mechanical system applications, while delivering reliable operation, lower operating cost and compact installation.

Provided in two- to six-ton (7.0 kW to 19.3 kW) capacities, The Tranquility 30 Digital (TE) Series unit with two-stage operation joins ClimateMaster's innovative line of water source heat pumps to integrate two-way digital communicating controls, two-stage capacity, variable-speed fan and internal variable water flow components within a single package.

Available with multiple cabinet options (vertical upflow, vertical downflow and horizontal), the Tranquility 30 Digital (TE) series unit with two-stage operation is flexible for a wide range of commercial projects. With an extended-range refrigerant circuit and capabilities for ground loop (geothermal) and water loop (boiler-tower) applications, it is among the industry's most versatile units currently on the market.

The Tranquility 30 Digital (TE) Series unit notably features ClimateMaster's DXM2 control board, with iGate™ and vFlow™ digital technologies that elevate it among competitive units in numerous respects. Additionally, microchannel aluminum air coils come standard on unit models 026 through 049.

"The Tranquility 30 Digital Series unit with new two-stage operation extends our provision of energy-saving heat pump solutions via the industry-exclusive vFlow and iGate technologies," said Raj Hiremath, director of marketing at ClimateMaster. "vFlow, which provides built-in water flow management, and iGate, which serves as the information gateway for the heat pump unit's operation, facilitate the Tranquility 30 Digital Series unit's lowest system operating cost of any single or two-stage water-source or geothermal heat pump on the market today."

The unit's integrated iGate™ (or "Information Gate") technology streamlines installation by allowing contractors to easily tailor the set-up of the unit, monitor its performance, custom-tailor its operation, and diagnose issues directly from the thermostat. By providing direct communication with the ECM blower, iGate can facilitate a technician's configuration of the unit's airflow from the thermostat, and without having to change DIP switches on the units control board.

Promoting reduced installation and labor time, optional vFlow™ (or "Variable Water Flow") integrates with the iGate system to enable the unit's operation at optimal capacity. The heart of vFlow™ is either an integrated variable-speed pump (for ground loop applications) or modulating water valve (for ground water applications) directly linked into the iGate™ system. Water flow is automatically varied based on changes in unit capacity level (or stage) and source water temperature to maintain optimum system performance, and protect the unit from extreme operating conditions. NOTE: This feature is unique in the industry to the ClimateMaster TE and TZ series.

In closed loop applications, vFlow's variable-speed internal flow controller can save 70 to 80 percent in water circulation costs in part load when compared to single-speed flow controllers. In open loop applications, the internal modulating motorized valve reduces installation complexity and pumping watts required by automatically delivering the required water flow. A low pressure drop version of the modulating motorized valve is also available for closed loop systems.

The Tranquility 30 Digital (TE) Series unit with two-stage operation features a Copeland UltraTech two-stage scroll compressor, with an industry leading double-isolation compressor mounting and sound-absorbing insulation to facilitate quiet operation. It additionally incorporates a variable-speed ECM fan motor, insulated divider and separate compressor/air handler compartments, galvanized steel construction, a standard stainless steel drain pan and a matte black epoxy powder-coated front access panel. Exceeding ASHRAE 90.1 efficiencies, the unit offers eight standard safety features, is available in horizontal and vertical configurations, and is capable of operation in a 20° to 120°F extended range.

The Tranquility 30 Digital (TE) Series unit with two-stage operation is available with a range of options, including a hot water generator, tin plated copper hairpin air coils to prevent formicary corrosion, extended-range insulation, an UltraQuiet package, a constant-speed internal secondary circulator, a field-convertible discharge air arrangement (horizontal units only), and an internally trapped condensate drain line (vertical units only),
