Chandler Manufacturing constructs each unit to our customers’ specifications. We do not build “cookie-cutter” equipment. Our sales and engineering staff can work with you do design a Hot Oil Unit that meets your specific needs. Several popular options are listed below.
 

Optional Equipment

  • Automatic Heater Hood Closers – hood closers prevent water and debris from entering the heater when it is not in use. They provide an additional safety measure by closing when the fire suppression system is triggered to help snuff out fires. Hood closers are standard on Oil-Fired Heaters
  • Stainless Steel Burner Tips (Propane-Fired) – withstand heat better and therefore have are longer lasting than standard carbon steel tips.
  • Insulated Vaporizer (Propane-Fired) – recommended for very cold climates, improves vaporizer efficiency.
  • Tank Level Float Gauge – indicates tank level without using sight glasses.
  • Sight Glass Washer – electric pump draws fluid from chemical tank to wash sight glass interiors.
  • Oilbath Chainguard – completely enclosed chain drive with oilbath lubrication for the High Pressure Pump decreases wear and tear on chain and sprockets.
  • Plunger Lubricator – ratcheting lubricator automatically lubricates High Pressure Pump plungers when pump is in operation.
  • Auxiliary High Pressure Pump Lube System – electric pump to boost oil pressure in High Pressure Pump power end, recommended for low-speed pump operation.
  • High Pressure Pump Relief Valve – adjustable or shear-pin type relief valve relieves excess pressure back to the pump suction or service tank.
  • Centrifugal Feed Pump – centrifugal feed pumps require less frequent replacement than Viking pumps and offer comparable performance when pumping water or light-to-medium crude oil. They often will have higher flow than a Viking pump but they are limited to about 175 PSI output pressure.
  • Flow Meter – electronic flow meter/totalizer piped into discharge line, or between feed pump and heater with bypass line. Displays current flow rate and records total volume pumped.
  • Electronic Temp/Press Gauges – Altronic digital panel gauges have adjustable set points and bright easy to read LCD readouts.
  • Aluminum Discharge Pipes – lighter and easier to handle than steel pipe.
  • Lift Axle – third axle can allow for additional weight without the need for a permit.
  • Hydraulics Package – hydraulically driven Feed and Load Pumps. Fewer driveline components to lubricate or adjust, allows for infinite pump speed adjustment.
  • Additional Fuel Capacity - additional "stacked - 250" fuel tank or other custom fuel tank designs for longer running time
