Keep Your TERI Unit Running Consistently

In order to maintain your TERI heater and keep it running at optimum efficiency, the unit must be properly maintained. The objective of the TERI Preventive Maintenance program is to minimize breakdowns, unscheduled repairs, and undue wear and tear. The TERI Preventive Maintenance Program includes the following:

Visual Inspection

  • Inspect any visible damage to the heater
  • Inspect any atmospheric corrosion
  • Inspect expansion tank
  • Inspect glycol level
  • Check for liquid leaks
  • Inspect skid (when applicable)
  • Examine condition of components (e.g. valves, regulators, gauges, relief valves, re-lighter system, flame arrestor,  and flame element)

Safety Check Inspection

  • Confirm level floats are functional
  • Check high and low gas pressure switched
  • Check heater high temp shut-downs for unit bath and gas
  • Check heater re-lighter (when applicable)
  • Inspect heater fuel gas pressure
  • Leak-check entire gas train
  • Check operation of heater and verify proper set points
  • Verify proper functionality of regulators and Kimray vents
  • Check heater stack guard and pilot guard (when applicable)
  • Review and analyze latest glycol report
  • Pull a glycol sample and provide it to the owner to obtain additional analyses

Combustion Levels Analysis

  • Check and provide printout of heater flue gas emissions
  • Remove burner and pilot and clean soot, rust, and corrosion from vessel
  • Check heater mixer for dirt and debris buildup
  • Check heater flame arrestor element and clean as necessary
  • Inspect heater ignition rod, clean nozzle and orifice, clean flame sensor rod, check heater ignition wires and ground and make necessary repairs
  • Remove clean-out tee on heater stack and inspect firetube for buildup

Heater Cycle Review

  • Observe heater cycle and document heater shutoff & cycle temperatures
  • Cycle temperatures on heater process gas
  • Test heater high temperature shut down and heater temperature controller on heater bath
  • Bypass the process temperature controller to observe shutdown

Documentation Report

We will conduct a documentation report that will include the date(s) and time of work, station name and address, model and serial number of the heater, model and serial number of subsequent peripheral equipment needing additional attention or replacement. The report will include general observation of the unit and overview of its operability. It will include recommendations if needed and all other information mentioned throughout this document. An example checklist for routine maintenance shall be provided for the specific unit, as will a recommended spare parts list.

Extend the Life of Your QuikWater Unit

The ultimate value of your QuikWater investment rests on the continued use of your equipment. The objective of the QuikWater Preventive Maintenance program is to minimize breakdowns, unscheduled repairs, and undue wear and tear. The QuikWater Preventive Maintenance Program includes the following:

QuikWater Equipment Inspection

  • Examine all structural components for signs of wear or excessive heat
  • Look for leaks and repair
  • Check all pipe fittings for leaks or damage
  • Repair if possible or provide customer with the part number and price for the replacement parts
  • Check all electrical components for loose or missing covers, loose conduit connections, etc.
  • Repair if possible or provide customer with the part number and price for the replacement parts

Internal Inspection

  • Empty and clean out the tank. Remove any debris and note any scaling
  • Check the internal structural components for signs of wear, excessive heat, or scaling. Look for leaks and repair
  • Check the burner and all related components for corrosion or damage. Repair if possible or provide customer with the part number and price for the replacement parts
  • Examine the packing and packing shelf. Note the amount of scaling present
  • Examine all nozzles. Remove any debris. Note any scaling. Recommend replacement of any worn nozzles

Additional Maintenance

Safety Test

Check all the safeties to assure that they are functioning properly. These safeties will include, but are not limited to:

  • High-temperature shutdown
  • Low-level shutdown
  • Combustion air pressure switch
  • Firing chamber flow switch
  • Low gas pressure shutdown
  • High gas pressure shutdown
  • Temperature controller
  • Loss of flame shutdown
  • UV Scanner flame detection
Operational Test
  • Run the heater and test all functions of the heater
Descale heater

Our service technician will perform internal heater cleaning using acidic chemicals to remove limescale using the following cleaning procedures:

  • Close the hot water discharge block valve to retain all water and cleaning chemicals on board the heater
  • Heat a full tank of water to 120 degF – 160 degF
  • Turn off fuel supply so burner cannot be relighted
  • Add cleaning chemical to heater’s water to run in Clean-in-Place mode (CIP). Approximate CIP mode runtime between 8-12 hours depending on scale buildup.
  • Cleaning chemical to be provided by others. OGI can provide cleaning chemicals at an additional charge.
  • Drain and flush cleaning solution

Documentation Report

We will conduct a documentation report that will include the date(s) and time of work, station name and address, model and serial number of the heater, model and serial number of subsequent peripheral equipment needing additional attention or replacement. The report will include general observation of the unit and overview of its operability. It will include recommendations if needed and all other information mentioned throughout this document.
