  • Page 5: Introduction

    The YLAA weighs less and has s smaller footprint than other chillers in its class. In fact, it is 20-35% lighter weight than the market average chiller. When the chiller is roof-mounted in new construction, the cost of the support structure can be reduced.
  • Page 6 YLAA also offers an efficiency choice. In addition to the high-efficiency units, YLAA chill- ers are available in standard efficiency models with smaller footprints and lower capital costs. Only pay for the chiller you need – the multi-efficiency levels of the YLAA allow you to decide the best investment for the job. Flexibility The YLAA chiller offers a number of options designed to operate reliably across a wide range of customer needs.
  • Page 7 Minimal maintenance is required to keep the unit operating at maximum performance. If service should ever be required, the YLAA chiller has been designed to simplify the work, keeping costs down. The layout of the chiller locates all the major components that can be serviced near the outside edge.

    FORM 150.72-EG6 (516) Equipment Overview The 55 - 175 Ton (195 - 615 kW) YLAA models are shipped complete from the factory ready for installa tion and use. The unit is pressure-tested, evacuated, and fully charged with a zero Ozone Depletion Potential Refrigerant R-410A and includes an initial oil charge. After assembly, a complete operational test is performed with water flowing through the evapo- rator to as sure that the refrigeration circuit operates correctly.
  • Page 9 FORM 150.72-EG6 (516) Equipment Overview (Cont'd) BRAZED PLATE EVAPORATOR The compact, high efficiency Brazed Plate Heat Exchanger (BPHE) is constructed with 316L stainless steel corrugated channel plates with a filler material between each plate. It offers excellent heat transfer performance with a compact size and low weight, reducing structural steel requirements on the job site.

  • Page 11 They feature ball bearings that are double-sealed and permanently lu bricated. UNIT CONTROL SYSTEM The YLAA chiller is designed with an intelligent control system that operates the chiller automatically with maximum reliability, safety and ease of use. The controls are factory tested and with as little user input as a chilled liquid setpoint the chiller will operate to meet the load demand.
  • Page 12 FORM 150.72-EG6 (516) Equipment Overview (Cont'd) Maximum reliability is achieved through intelligent control. Run hours and starts are av- eraged across all compressors automatically, and between both pumps of the optional dual pump hydro-kit. When compressors are cycled off, an anti-recycle timer ensures the motors have time to cool before starting again, for the maximum service life.
