AB-QM, Pressure Independent Control Valve
|
|
|
These valves can be used separately for automatic flow limiting or, when fitted with an actuator, can serve as combined flow limiter and control valve. Setting is extremely user friendly and reliable. AB -QM valve applications include balancing and controlling terminal units such as fan-coils, chilled ceilings, and air handling units. Setting is made quick and easy for the installer. Fitting with a Danfoss actuator upgrades the AB -QM to a full-function control valve for both temperature control and flow balancing.

Electronically Controlled Bypass
|
|
|
The Danfoss Electronically Controlled Bypass (ECB) incorporates HVAC-specific features such as automatic bypass, common start/stop, coordinated run-permissive, and serial communications over the BAS as standard. Unique among microprocessor-based bypass products, the ECB uses the same keypad for both drive and bypass functions. The ECB centralizes I/O and logic tasks into the VFD package. In many cases, this means retrofit installations can easily take advantage of new functionality with minimal changes to the BAS system. Using the next generation VLT HVAC Drive, now available with BTL -certified BAC net, the ECB represents Danfoss’ ongoing commitment to customer applications.

AKD 102 Drives for Commercial Refrigeration
|
|
2009 AHR Expo Innovation Award Winner!
The energy-saving AKD 102 provides exact load matching for commercial refrigeration, and is the industry’s first variable capacity drive that is programmed using refrigeration terms familiar to refrigeration technicians rather than computer electronics people. A setup “Wizard” and on line manual also simplify work for OEM, installer, and service technicians. The AKD 102 drive was honored with the 2009 AHR Exposition’s Innovation Award for Refrigeration.

LX Electric Floor Heating
|
|
|
Installed by quickly rolling out on almost any sub-floor, the LX floor heating mat is made of a durable fiberglass material that can withstand the rigors of a job site and is easily cut around obstacles like toilets, sinks, and cabinets. Unique in the industry, the mat is self-adhesive, and needs no other adhesives, eliminating a time-consuming step from the installation process. Our electric floor heating systems were designed with the installer in mind, with pre-applied heating cable, single point connection, and self-adhesive backing, all leading to quick installation and trouble-free service with a 10-year warranty.

Scroll Compressors
|
|
|
Danfoss offers a wide range of scroll compressors for both air conditioning and refrigeration applications. In many applications, scroll compressors offer significant advantages over reciprocating designs. Axial and radial compliance in Danfoss scroll compressors result in great energy efficiency with extended service life. The simple yet effective scroll design requires many fewer moving parts, no internal valves, unmatched ability to handle liquid refrigerant, and limited wear.

XGE Fan Speed Control
|
|
|
New compact and precise Danfoss Saginomiya XGE fan speed controllers can be used in the smallest refrigeration units to provide energy-saving and repeatable fan speed control as condensing pressure varies, ensuring stable system operation. XGE controllers have innovative features that help in installation and setting, with wiring diagram and a setting aid embossed on the control. They can be installed directly on the refrigerant line or on an accessory mounting bracket.

APEXXTM VSH Variable Capacity Scroll Solutions
|
|
2009 AHR Expo Innovation Award Winner!
For commercial air conditioning, Danfoss offers a unique new solution: the first high capacity scroll compressor for R-410A, mated with a variable frequency drive. Designed and manufactured specifically for each other, and crafted to deliver exactly the capacity required for cooling every minute of the day, their performance sets a new standard. VSH solves the problem of wasted energy at partial load—the load condition about 70 percent of the time. Energy savings with VSH can exceed 20 percent. The delivered capacity range is from 3.5 to 23 tons. The APEXX VSH solution was honored with the 2009 AHR Exposition’s Innovation Award for Cooling.

Turbocor Oil-Free Compressor
|
|
The world’s first totally oil-free centrifugal compressor line, specifically designed for HVACR, is expanded for larger capacity equipment and additional applications.
- The new TT500 delivers 210 tons (700 kW) nominal cooling capacity and along with the TT300 and TT400 is predominately designed for water-cooled systems.
- The new TT350, with nominal cooling capacity of 120 tons (400 kW) is designed for higher pressure ratios, particularly in air cooled applications.
- Turbocor compressors are 45-55% more energy efficient than others in their size class, and also the quietest available. All compressors have a soft start that draws only 2 A.

|
|
A clear view of flowing refrigerant, together with a humidity indicator lets you keep an eye on your system’s refrigerant. Lighter and more compact than traditional sight glasses, SG+ models have a wider viewing area and the finest indicator available, and are the industry’s only sight glasses formed from deep-drawn stainless steel. Available in a range of sizes from 1/4 to 7/8 in., in flare, sweat, and socket body styles. With a maximum working pressures up to 667 psig, the new SG+ family are suitable for today’s environmentally friendly high pressure refrigerants. Because they are stainless steel, they are little affected by brazing heat and operating ambient.

Refrigeration Scroll Compressors
|
|
|
A new highly efficient, reliable, low noise refrigeration scroll compressor range has been added to the Danfoss line of refrigeration solutions. MLZ scroll compressors include 11 models of medium temperature scroll compressors designed for ice machines, soft serve ice cream machines, cold rooms, milk cooling tanks, compressed air dryers, and other light commercial refrigeration applications. The MLZ’s hybrid wrap scroll design increases compressor displacement to provide higher capacity without increasing package size. Adaptive axial scroll member compliance increases efficiency by minimizing losses due to friction. The design provides a soft start so that in most applications, no start capacitor is needed.
