TSE

Range: 23÷309 kW

TSE is the HiRef range of liquid chillers with remote condenser and Scroll compressors. These motoevaporating units are available with different refrigerating set-ups (Efficiency Packs), numerous power ratings and two different noise emission set-ups, making them particularly versatile for application in various plant engineering contexts. Sizing, the choice of individual components and control of auxiliary units (circulation pumps, remote condenser fans) aims to reduce energy consumption and extend energy savings throughout the system. The TSE range also features the multiscroll solution (also on single circuits), electronically controlled expansion valves and the option of managing the circulation pumps and remote condenser fans via on-board software: all these characteristics allow achievement of high energy efficiency at partial loads. Controlling oil return via integrated software logic helps boost the reliability of the compressors and, therefore, the unit. The carefully arranged component layout, together with compact plate heat exchangers and the Scroll compressors, gives the machine a compact configuration and makes it adaptable to any installation area. Sizes with EFFICIENCY PACK 1 and 2 (compressor tandem on single circuit and dual circuit) also have a width compatible with that of most doors, making transport and installation easier. Scroll compressors, which are the main noise source in the unit, are fitted on rubber feet; these absorb vibration and therefore attenuate the noise transmitted to the various system parts. On request, the compressor compartment can be lined with special soundabsorbing material and the compressors wrapped in special insulating hoods to reduce airborne noise emissions. TECHNICAL CHARACTERISTICS Scroll compressors Refrigerating circuit configurations: -EFFICIENCY PACK 1 (from 47 to 190 kW): dual compressor on dual circuit for high system redundancy. -EFFICIENCY PACK 2 (from 46 to 190 kW): dual compressor (tandem) on single circuit for greater efficiency at partial loads. -EFFICIENCY PACK 4 (from 146 to 478 kW): four compressors (dual tandem) on dual circuit, for a system that is simultaneously redundant and efficient at low loads. -Sizes above 478 kW are always of the dual refrigerating circuit type with five or six Scroll compressors. Electronically controlled expansion valve as standard Braze-welded stainless steel plate heat exchangers Easy connection with Vic-Taulic type couplings Remote condenser fan control for air flow modulation Remote pump control according to constant T or constant ΔT logic Partial heat recovery (desuperheater), optional Kit for oil recovery from refrigerating lines up to 60 m long Second set point, on utility side, able to be activated from external input
