COMFORTECH PRODUCT SHOWCASE AWARD

At HVAC Comfortech 2012, 13 products were recognized as Product Showcase Award winners. Judges took into consideration the ease with which HVAC contractors can apply the technology, and the technical value of the product or service to the HVAC industry. We’ll feature these products each month in upcoming issues of Contracting Business.com. This month, we’re featuring ClimateMater’s Tranquility 30 heat pump, the winner in the Forced-Air Heating category. For additional information on any of the products listed here, circle the appropriate number(s) on the reader service card at the back of this issue or visit www.contractingbusiness.com/freeinfo.html.

ClimateMaster Releases the Tranquility 30 Digital Series

The Tranquility 30 Digital (TE) joins the Tranquility 22 Digital (TZ) as a geothermal heat pump product lines that integrates digital communicating controls, two-stage capacity, variable-speed fan and variable-flow geothermal source functions within a single package.

The heat pump uses iGate and vFlow technology. iGate technology is the next generation in intelligent control by using two-way communication to provide a gateway into the system. The iGate control system allows end-users and contractors to monitor the performance of the unit, custom tailor its operation, and diagnose any issues, right from the thermostat.

The iGate communications hub is the new DXM2 intelligent controller, which analyzes the status of sensors and smart components (which are also two-way communicating) to determine how best to operate the system for optimal comfort, efficiency and long-term reliability. All of this information is passed to the iGate thermostat (or dealer diagnostic tool), where it can be displayed in plain English. And since communication is both ways, the iGate thermostat can also be used to configure and tailor the system without even touching the unit.

Taco Offers New Differential Pressure Sensors

Taco has added a new differential pressure sensor to their extensive line of hydronic system components. The sensor relays system performance information to a VFD or to a building management system.

The Taco DPS629 monitors differential pressures of air and compatible gasses and liquids. The design uses dual sensors that convert pressure changes into a standard 4-20 mA output signal for two-wire circuits. Its small size and few moving parts make for exceptional response time and reliability. Terminal block, zero, and span adjustments are easily accessed under the top cover. Designed to meet NEMA 4x (IP66) construction, the unit is applicable for flow elements, heat exchangers, filters, pumps and coils.

New Alarm Helps Prevent Air Conditioner Theft

The ACAL-SHARK is the first alarm of its kind that doesn’t require an internal control panel. According to company sources, this allows for the easy installation.

The ACAL-SHARK is a stand-alone siren that runs off 12v DC, and has an optional battery backup. It also contains a tamper switch that will activate if the siren is pulled from the wall or the cover is removed. There are four wires coming out of the siren that are used for installation. Two wires connect to the included 110v AC to 12v DC converter, and the other two connect to the sensors on the unit.

If any of the wires are tampered with or cut, the power is disconnected, and if pressure falls below 5 psi the siren will sound. The system also features a refrigerant monitor, as an add-on feature. Other accessories include tilt sensors and the ability to connect the unit to an existing central alarm system.

Danfoss Introduces the 435 Series Actuator for the AB-QM Pressure Independent Control Valves

Danfoss releases its new generation of 435 series actuators, which will replace the prior AME 15QM series of actuator for the Danfoss AB-QM pressure independent control valve (PICV).

The AME 435QM and AMV 435 are the first of a new design of actuators, which offer improved operation with lower power consumption. This new family of actuators requires no additional tools when it’s installed to the AB-QM valve bodies. The click-on mounting mechanism of the actuator reduces actuator installation time.

Standard features for these new actuators include two selectable operation speeds, external LED for visual confirmation of actuator operation, end travel LED signaling and easy calibration via an external reset button. The 435 series of actuators are smaller and lighter than our previous model with 24 volt AC or DC power capabilities. ABQMvalves.com
