Comfortech Product Showcase Award

At HVAC Comfortech 2010, 12 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. This month, we're featuring LG's Flex Multi Split, the winner in the Zoning Equipment 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

LG Flex Multi Split Raises the Bar in Zoning Equipment
LG's Flex Multi-Split system can operate up to four interior units mounted in separate rooms for easy temperature control in each setting, but all connected to one single exterior condensing unit.

Furthering its commitment to providing energy efficient technologies in its products, LG uses an advanced inverter compressor technology and an environmentally-friendly refrigerant in its systems. LG has also incorporated the advanced inverter technology with its line of Multi-V systems which use a variable refrigerant flow (VRF) heat recovery system to operate cooling and heating simultaneously with one outdoor unit for easy temperature zoning.

LG's advanced inverter technology uses inverter heat pump air conditioners with a variable speed compressor, rather than the constant speed found in conventional air conditioners. LG's Flex Multi-Split Quad-Zone system comes with four interior units that can be mounted in separate rooms for enhanced temperature controls. Connected to a single exterior condenser unit, these units provide easy zoning across a variety of environments.

Continental Fan Introduces AMP Motorized Panel Fans
Continental Fan's AMP motorized panel fans feature superior performance in a compact design. According to company sources, they're ideally suited to applications where space is limited. The unique coupling of motor and impeller minimizes space requirements and provides for vibration free operation.

AMP fans are completely speed controllable. Both motor and impeller are located directly in the air stream, where the impeller acts as a rotating "heat sink" with excellent heat dissipation and efficient motor cooling. Near zero speeds can be achieved using solid-state speed controls.

Continental Fan offers a complete line of axial and centrifugal motorized impellers with AC, DC or EC high efficiency motors, in a choice of housed or non-housed units.
