PORTABLE TRANSFORMER OIL COOLING SYSTEMS

DESCRIPTION:  Baron USA portable transformer oil cooling units are designed to circulate transformer oil in and to provide supplemental cooling to a transformer.

FLOW RATE:  The flow rate is adjustable from 0 to 30 gallons per minute through the use of a bypass globe valve.

OIL COOLING CAPABILITY:  is provided by a Horizontal Air/Oil fan cooler with the following features:

·         Fan: 6,600 cfm @ 0.9” TSP with 3 HP motor

·         Internal fan isolators

·        Flat filter section with 2” cleanable filters

·         Internal fan isolators

·        Valved and plugged air vent at oil fill high point

·         Heat removal: approximately 340 MBH (based on 80C / 176F entering @ 30 gpm; oil leaving oil at 68C / 155F with 95F ambient).  Will vary with inlet conditions, flow rate and ambient temperature.

PUMP: Self-priming crescent gear pump with integral relief valve

SUCTION STRAINERS:  with mesh basket and magnetic plug on both inlet and outlet

FLOW SIGHT INDICATOR:  located in the line between the pump and cooler

FLOW RATE METER:  with local rate display and with low flow switch interlocked with indicator light and automatic pump stop

ACCUMULATOR (EXPANSION TANK):  Allows for the oil expansion/contraction during storage with closed valves

GAUGES: Inlet and outlet local temperature gauges; one panel-mounted inlet temperature gauge, local pressure gauge on oil pump discharge

PIPING:  All steel welded pipe insures years of leak free service. Threaded connections are eliminated except where component removal requires it.  All ball valves have stainless steel balls with Teflon seals. Butterfly valves are used for vacuum service and have Viton seats and seals.

BASE:  The entire system is mounted on a reinforced structural steel base with integral drip pan to collect any oil that may be accidentally spilt during filter element or vacuum pump fluid change-out.

CONTROLS: Central Nema 4 enclosure containing pump and cooler starters, on/off pushbuttons for pump and cooler

CABLE REEL: Control panel connected to a 45-amp spring-rewind live cable reel with 50’ portable cord with flying leads at the free end for 240/1/60 power (34 A approx. FLC).

HOSES:  1-1/2” or 2” (your preference) suction and discharge hoses, hard-connected to trailer inlet and outlet; SS overbraid hose x 20’ long each.

DOCUMENTATION:  An Operating and Maintenance manual with spares list and warranty is provided on DVD.

PORTABILITY:   Every portable transformer oil cooling unit is available in a stationary model or can be made portable on a trailer.
