Portable Oil Heating-Pumping & Vacuum Systems
Model BA-OHM,VPM and OHVM Series

Function

These economical Baron units are compact, light and portable systems for the assisted heat up of transformers being dried in the field. They can be used to preheat or boost heat by hot oil circulation prior to or during processing with a Baron oil purification trailer.

Systems are available with:

• A wide variety of circulating pump sizes
• A wide range of heater sizes
• Optional particulate filtration
• Vacuum systems for pumping vacuum on the apparatus during heat up

Product Descriptions

OHM – Oil Heating Module

This module consists of a high-quality oil-circulating pump, in the flow rate of your choice and a bank of low watt-density heaters in the capacity of your choice. All heater and pump controls are included, as well as system safety devices and alarms.

VPM – Vacuum Pumping Module

This module consists of a high-quality, two-stage vacuum pump and vacuum booster combination in the CFM capacity of your choice.

OHVM – Oil Heating/Vacuum Module

This module combines the features of both the OHM and VPM onto a single system with integrated controls.

Standard Components

OHM

• Heavy-duty, positive-displacement, direct-driven oil pump with relief valve
• Low watt-density heaters designed for efficient heat transfer while protecting oil from scorching. Heaters are controlled automatically to maintain the desired setpoint by a solid state temperature and step-control system
• Inlet suction strainer to protect the oil pump from the ingress of large particles
• System pressure gauge
• Rate of flow indicator
• Inlet and outlet isolation valves
• Inlet and outlet camlock couplers with dust caps

VPM

• Heavy-duty, rotary piston vacuum pump with gas ballast valve
• Roots-type vacuum booster with internal bypass for startup at atmospheric pressure and fast pump-down oil trap to protect the vacuum pumps from the oil overflow into the vacuum piping
• Electronic vacuum gauge
• Anti-suck-back valve to protect vacuum loss in the system in the event of power loss
• Inlet isolation valve
• Inlet camlock couplers with dust caps

OHVM

• All of the features of the OHM and VPM modules are combined into a single unit with centralized controls for all components
• Operating and maintenance manuals are included with all systems

Electrical Requirements

• All systems are available in every standard three-phase voltage up to 600 V in either 50 or 60 Hz. Specify desired voltage at time of inquiry.

Accessories

A full range of accessories is available for these systems, including:

• ASME code design (labeling available upon request) filter housing for particulate removal in the oil circulation loop. This filter uses industry standard 6" x 18" pleated paper 0.5 micron elements and is sized according to the desired flow rate.
• Cuno Zeta Plus filter housing and elements
• Totalizing meter
• Oil and vacuum hoses
• Weatherproof housing
• Open-type or van-style trailer
