Water-Cooled Condensers - HTS

D. Evaporator: The evaporator shall be two circuit, direct expansion, shell-and-tubetype with copper tubes rolled into steel tube sheets. It shall be insulated with 3/4inch (19 mm) closed cell polyurethane insulation and designed for 150 psi (1034kPa) water side working pressure and 354 psi (2441 kPa) refrigerant side pressure.It shall be designed in accordance with ASME Pressure Vessel Code, Section VIII,and have ANSI B9.1 pressure relief valves.OPTION: The evaporator shall have 1 1/2 inch (40 mm) closed cell polyurethaneinsulation in lieu of standard 3/4 inch (19 mm).OPTION: The evaporator shall have left-hand water connection when viewed fromthe control panel.E. Condensers: Horizontal shell and finned tube type with steel shell and integralfinned copper tubes rolled into steel tube sheets. The condenser shall be equippedwith intermediate tube supports and construct in accordance with the requirementsof ASME Unfired Pressure Vessel Code Section VIII and ANSI B9.1 Safety Code.It shall be designed for 225 psi (1551 kPa) water side working pressure and 350 psi(2413 kPa) refrigerant side pressure. It shall have ANSI B9.1 pressure reliefvalves..F. Refrigerant Circuit: The unit shall have two or more refrigerant circuits, completelyindependent of each other. Each circuit shall be equipped with one compressor withintegral oil separator, one microprocessor controller, a factory-mounted controlcircuit transformer, electronic expansion valve, compressor suction shutoff valve,discharge check valve, liquid line shutoff valves, replaceable core filter-dryers,sight-glass with moisture indicator. Each circuit shall be capable of operatingindependently, not being disabled in the event of fault(s) on the other circuit(s).OPTION: Each compressor shall have a suction service shutoff valve.G. Electric Panel: The electric panel shall consist of two separated compartments,one for power components and one for control components. The control sectionshall contain a microprocessor controller for each circuit and one for the unit,providing operating and equipment protection controls. The circuit controllersshall operate independently of each other.OPTION: The panel shall include a 115-volt convenience outlet.The power section shall include solid state motor starters, a control transformerwith primary and secondary fusing, microprocessor transformers with fusing,standard power blocks for each electrical circuit power connection, andswitches for each circuit pumpdown and unit control power. The control panelshall have a hinged, tool-locked door.OPTION: The unit shall have power connection to factory-installed, non-fuseddisconnect switches with through-the-door handles for each electric circuit.OPTION: The unit shall have power connection to factory-installed, highinterrupt current rated, non-fused disconnect switches with through-the-doorhandles for each electric circuit.OPTION: The unit shall have a high short circuit rated panel with high interruptcurrent rated, non-fused disconnect switches with through-the-door handles foreach electric circuit.OPTION: The unit shall have single point power connection to a factoryinstalledpower block that is factory-wired to compressor isolation circuitbreakers for each circuit.OPTION: The unit shall have single point power connection to a factoryinstalled,non-fused disconnect switch with through-the-door handle. Eachcircuit shall be equipped with factory installed compressor isolation circuitbreakers.OPTION: The unit shall have single point power connection to a factory-Catalog WGS-1 WGS 130A – 190A 57
