Dart Helicopter Services' announces that their subsidiary partner Apical Industries, Inc. has added the AS350 Air Conditioning Kit to their expanding product line. Transport Canada and EASA approvals are pending.

The AS350 Air Conditioning Kit is a complete cabin cooling solution that offers a lightweight reliable cooling system with no negative effect on aircraft performance. Apical Industries surveyed various operators about the shortcomings of their current systems and incorporated numerous improvements to address these concerns.

The kit is a lighter and more reliable alternative to currently certified systems. All of the main components are mounted on the transmission deck, allowing full use of the baggage compartment and increasing ease of maintenance. All of the major components can be removed for missions that do not require air conditioning. The Condenser and Evaporators are state of the art aluminum microfin heat exchangers, which allow for much higher efficiencies, lighter weight, and a more compact design than other systems. A single evaporator replaces the current double evaporator design, saving weight but providing the same cooling capacity. Additional overhead ducts are installed to cool the pilot and copilot from both directions.

A variable displacement Compressor increases the efficiency of the system by automatically sensing the heat load and compensating for it by either increasing or decreasing the rate of refrigerant going through the system, thereby reducing power consumption and increasing the life of the compressor. Stronger compressor brackets have improved fatigue resistance over current systems, and are adjustable to allow for precise tensioning of the belt.

The Condenser fan has been designed with a stainless steel hub to prevent fan failure and improve service life.

Benefits:

• Reduced kit weight compared to OEM kit

• No loss of baggage space
