Insulation

All low temperature surfaces are covered with factory installed 3/4 inch (19.05 mm) Armaflex II or equal (k=0.28) insulation, including the evaporator and water boxes, suction line, and motor housing. 3/8" foam insulation is used on the liquid level sensor and gas pump assembly, including piping.

Low-Temperature Evaporator Addition of an oil cooler to the oil circuit enables evaporator operation down to minimum leaving water temperature of 10°F (-12.2°C).

High-Temperature Condenser

Addition of an oil cooler to the oil circuit enables condenser operation up to maximum leaving water temperature of 114°F (45.6°C).

Smooth-Bore CondenserTubes Smooth-bore copper or premium cupro- nickel condenser tubes, 3/4" (19.05 mm) in diameter with .035" (0.889 mm) wall thickness, are available for high fouling water applications.

Refrigerant Isolation Valves Factory-installed condenser inlet and outlet refrigerant valves allow isolation of the full refrigerant charge in the condenser while servicing the chiller.

Marine Water Boxes

Addition of marine water boxes for the condenser allows tube cleaning without water pipe interference.

300 psig Evaporator and Condenser Water Boxes

Water boxes are designed for 300 psig maximum waterside working pressure, and grooved pipe water connections are provided for ease of installation.

2-Way CondenserWater RegulatingValve

For water regulation, a field-installed,

2-way butterfly-type (lug-style) valve, with integral electrical operator and factory-mounted valve actuator, is available.The single-phase, reversible motor can be factory-wired for 115VAC, 60 Hz or 220 VAC, 50 Hz; the 2-way valve is field-wired and controlled by the chiller regulating valve control output; valves are available in 6" and 8" (152.4 and 203.2 mm) sizes.

Nitrogen Charge

Unit is shipped with a nitrogen holding charge in lieu of refrigerant.

Seal Kit for Reassembly

Ideal for situations when the bolt-together construction of the RTHD will be separated for installation, this seal kit provides replacement gaskets and rings for reassembly.

Solid State Starter

Solid State Starter is unit-mounted with a NEMA 1 gasketed enclosure.To extend starter life, contactors bypass current from the silicon control rectifiers (SCRs) after startup.

Under/Over-Voltage Protection Unit receives protection against variations in voltage (current lag and spike protection is standard).

Performance andWitnessTests ARI-certified RTHD Performance and WitnessTests are available, based on requested operating points, to certify chiller performance before delivery.

Main Power Disconnect Options:

Non-fused Disconnect

A UL-approved non-fused molded case disconnect switch, factory pre-wired with terminal block power connections and equipped with a lockable external operator handle, is available to disconnect the chiller from main power.

Standard Interrupting Capacity Circuit Breaker

A UL-approvedstandard interrupting molded case capacity circuit breaker, factory pre-wired with terminal block power connections and equipped with a lockable external operator handle, is available to disconnect the chiller from main power.

High Interrupting Capacity Circuit Breaker

A UL-approved high interrupting molded case capacity circuit breaker, factory pre- wired with terminal block power connections and equipped with a lockable external operator handle, is available to disconnect the chiller from main power.

Ground Fault Circuit Breaker

A UL-approved standard interrupting molded case capacity circuit breaker with ground fault interrupting capability, factory pre-wired with terminal block connections and equipped with a lockable external operator handle, is available to disconnect the chiller from main power.
