SuperSleeve Expedites Mini-Split AC Installations

The SuperSleeve saves time, money and labor when retrofitting any brand or model of wall-mounted ductless mini-split evaporators in residential and commercial buildings.
Designed and developed by Marketair’s engineering department, the patent-pending, SuperSleeve eliminates the need for a second jobsite technician or a temporary support bracket to hold the evaporator in place during a retrofit installation. The 3-inch-diameter (I.D.) (7.5-cm) SuperSleeve is flanged on both ends for a tight, secure fit and telescopes from 6 to 12-inches (15 to 30-cm) to accommodate most wall thicknesses. 

The SuperSleeve design goes beyond conventional wall sleeves and features an innovative integral positive slope guide for the condensate drain hose. Although the sleeve is installed level, the drain hose guide sill ensures a 3/8-inch (9.5-mm) downward pitch away from the evaporator to promote correct drainage. The hose compartment at the bottom of the sleeve holds standard insulated 5/8-inch (16-mm) condensate hose securely in place to ensure the pitch.  

SuperSleeve is available direct or through most wholesale HVAC distributors throughout North America. For more information or to receive a free Marketair HVAC/R products catalog, please visit, call (732) 985-8226 or email:

Advanced modulating technology in new Champion® LX Series 16 SEER heat pump contributes to lower operating costs.

Available this April, the new Champion® LX Series 16 SEER/9.0 HSPF heat pump from Johnson Controls features advanced modulating technology proven in Champion’s five-year accelerated test facility and more than 215,000 hours of research.

The unit’s ability to adjust its operating capacity provides quiet, efficient operation as it adjusts heating and cooling levels up or down to provide only what is actually needed to condition the space. This provides more even temperatures and lower operating costs.

Reducing compressor speed and decreasing airflow also allows the system to operate longer without drastically over-cooling the space, improving dehumidification. In colder weather, a demand defrost feature minimizes heat pump operation, removing frost on the outdoor coil far more effectively than time methods.

Contractors will appreciate easy access to commonly serviced items, a sturdy fan guard, smooth edges that allow for easier handling and a compact footprint for easy hand trucking and placement on site. The unit also features Champion’s new fee-free, one-year labor limited warranty and is available in early 2016.

EcoNet's IOT Wireless HVAC Vent Receives SmartThings Approval.

EcoNet Controls of Clearwater Florida, a manufacturer of Home Automation Devices, has received the "Works with SmartThings" stamp of approval for its EV100 series of Z-Wave HVAC vents. A basic configuration of EcoNet's wireless vents and a SmartThings controller adds convenience and improved HVAC comfort and efficiency to the standard home. The EV100 joins a growing list of IOT devices that are compatible with SmartThings.

Although the EV100 is certified by the Z-Wave Alliance, it is a unique device that currently does not fit into any of the standard device categories. Because of this, changes were required in the way it communicates to the SmartThings controller. As an official partner, EcoNet worked closely with SmartThings in creating a custom driver for the EV100. The EV100 works with most standard Z-Wave controllers but it works especially well with SmartThings.

EcoNet's HVAC Vents/Registers are direct replacements for vents in the standard North American home that uses a forced air system. Installation and setup is simple and takes only a few minutes. The vents are available in several sizes and styles. A properly configured system can reduce HVAC cost from 10% to 20%.

Introducing the SRP MODULUS™ Adaptive Modulating Infrared Tube Heater.

The SRP Modulus™, adaptive modulating infrared tube heater provides unparalleled thermal efficiencies

Greenheck ICD Dampers Earn AMCA Efficiency Rating.

Greenheck’s ICD series of Insulated Control Dampers have earned AMCA’s new certified rating of Energy Efficiency. This new test method, which is found in ANSI/AMCA standard 500D-12, assigns a damper a Thermal Efficiency Ratio (E) by comparing its thermal performance with the thermal performance of a standard reference damper.  

In addition to being certified for energy efficiency, the performance of ICD series dampers is also AMCA certified for pressure drop and leakage. Greenheck Model ICD dampers are ultra-low leakage dampers with thermally broken insulated blades and available with a thermally broken frame. ICD dampers are ideally suited for applications where minimal leakage and thermal transfer are required or when condensation on the damper blades is a concern. Greenheck Model ICD dampers are licensed to bear the AMCA Seal for Air Performance and can help building projects qualify for LEED credits.

MSD Research, Inc., an innovator of HVAC products announced the launch of its ALL-ACCESS Condensate Cleanout Device.

The Model AA1 device installs easily into ¾” or 1” PVC drain lines in either the horizontal or vertical position. Once installed, the technician will never need to cut the drain line again to service it.

The ALL-ACCESS device allows the drain line to be cleared by attaching a nitrogen hose to the top fitting and clearing the drain line downstream from the unit. The flapper assembly inside the device automatically closes to seal off the drain leading back into the unit. Once the nitrogen pressure is removed the device remains completely open and permits the full flow of condensate.

The AA1-INS fits the device perfectly making it easy to install and also creates a better appearance.  This device will be available to the wholesale trade this August. We believe that this product will help HVAC companies save time and money and make drain line service a breeze.

Greenheck’s Vektor®-HS with SAVVE Technology Reduces Operating Costs.
Greenheck’s latest addition to the Vektor® laboratory exhaust fan line, the Vektor-HS with SAVVE technology, reduces fan energy consumption and operating costs in variable volume or demand-based laboratory ventilation systems.

Sure-Aire™ Variable Volume Exhaust or SAVVE technology incorporates the Sure-Aire noninvasive flow monitoring system that measures pressure drop across a fan’s inlet venturi. As airflow through the fan varies, SAVVE technology automatically adjusts the nozzle discharge area to maintain a constant and safe discharge velocity (minimum 3,000 ft/min per ANSI Z9.5) while energy consumption of the exhaust fan is reduced regardless of the laboratory exhaust airflow.

Benefits include reduced fan energy, reduced horsepower, and lower sound levels while maintaining proper pressurization of occupied spaces. Building exhaust systems incorporating SAVVE technology may qualify for energy rebate programs and Energy and Atmosphere and Outdoor Environmental Quality LEED™ Credits.
