The choice to install scroll compressors in a tandem or trio configuration on the same cooling circuit is a move in the right direction in terms of machine efficiency at partial loads, which is the normal operating condition for air conditioning systems.

Advantages

• Completely configurable range
• Incorporable hydronic kits
• HyBlade® fans
• Tandem and trio solutions for high efficiency at partial loads
• Remote connectivity with the most common protocols

• Structure
  Made in galvanised steel sheet with a polyester powder coating for outdoors. Base with reinforcement modules for eliminating any deformities resulting from impacts sustained in the transportation and handling phase.
• Scroll compressors
  Scroll type compressors in a tandem or trio configuration that can be sound insulated. The adopted components’ efficiency, reliability, and noise emission levels represent the state of the art for scroll compressors.
• Electronic microprocessor controller
  In standard or advanced version, it enables the complete control of the units. It can be easily accessed through a polycarbonate flap with IP 65 protection rating. The electronic control system allows the setpoint to be adjusted automatically according to the outdoor temperature in order to reduce consumption and broaden the working temperature range. The advanced version makes it possible to construct LAN networks for the parallel control of 4 units and the management of BACNET and LON communication protocols, as well as the modulation of the pump assembly, of the Smart Defrost System.

• Fan drive assembly
  Electric fan with 6-pole external rotor motor directly keyed to the axial fan, with internal thermal protection on the windings, complete with safety grille and dedicated supporting structure. Electric fans with BLDC motor are available on request.
• Heat exchanger
  Made of 8mm diameter copper pipes and aluminium fins. The special engineering of the heat exchangers allows defrost cycles to be carried out at maximum speed in the models with heat pump operation, which brings clear benefits in terms of the integrated efficiency of the whole cycle.

The models are completely configurable by selecting the version and the options. An example of configuration is shown below.
