Heaters

Heaters for forced circulation against hot melt heaters

Constant coolant circulation eliminates hot spots that damage heater hoses, damage engine seals and reduce coolant life. Forced circulation heaters, such as HOTflow ™ heaters, use an integrated pump to circulate the coolant through the engine to keep it at a more even temperature than standard convection heaters.

Our daily lives have become dependent on having power readily available 24 hours a day, seven days a week. Critical facilities such as hospitals, banks, transit authorities, gas stations, hotels, cell phone towers, high rise buildings and others depend on backup power in emergencies to keep their operations going. In an emergency, backup generators in these types of applications must start and accept full load power within ten seconds. HOTSTART engine heaters make that happen.

Heating coolant and keeping it circulating in an engine block when it is in standby mode keeps the generator ready to start at a moment's notice. HOTSTART’s wide range of heating solutions for generators includes traditional convection-based heating systems as well as efficient pump-driven models. Ensure your facility is ready to stay powered when it matters most with HOTSTART heaters.

Installation Instructions for Thermosiphon Engine Heaters

The HOTSTART engine heater uses thermosiphon action – the natural expansion and rising action of a heated fluid – to circulate heated coolant throughout an engine’s water jacket. Installation of the heating system is critical. Please refer to specific instructions that accompany your HOTSTART engine heater or visit hotstart.com and select Installation Instructions, Manuals and Guides from the Resources tab.

For “V” engines larger than eight cylinders or over 1000 CID (15L), HOTSTART recommends using a HOTflow® heater. Please refer to pages 4-5 for heater selection.

Prior to heater installation, inspect the coolant supply. When mixing coolant, only use deionized or distilled water and low-silicate antifreeze. Refer to your engine’s manufacturer recommendations. Do not exceed 60% antifreeze to 40% water ratio. Never add unmixed water and antifreeze to an engine. Do not add anti-leak or other coolant additives.

PREPARING

Drain and flush cooling system to remove any debris present in the engine’s cooling system.
Select return port. The return port will allow heated coolant to return to the engine.
Select supply port. The supply port will allow coolant to flow from the engine to the heater.
Select fittings. Use the following table to determine the proper port fitting size for your heater:

CB/CL/SB/SL	500–3000 watts	1/2 inch NPT
CB/CL/SB/SL	3750–5000 watts	3/4 inch NPT
WL/EE	1500–5000 watts	3/4 inch NPT

Select hoses. Use the following table to determine the minimum hose inner diameter for your heater:

CB/CL/SB/SL	500–3000 watts	3/4 inch
CB/CL/SB/SL	3750–5000 watts	1 inch
WL/EE	1500–5000 watts	1 inch

HOTSTART recommends installing valves to isolate the heating system in case of service. To minimize flow restriction, select full-flow ball isolation valves.

MOUNTING

Select a heater mounting position directly below the return port and at least 6 inches (15 cm) below the lowest point of the engine’s water jacket. Mount heater using the supplied mounting brackets and fasteners.

PLUMBING

Install isolation valves to port fittings.
Route and install return hose. The return hose should continuously rise from the heater to the return port.
Route and install supply hose. The supply hose should continuously descend from the supply port to the heater.
Refill cooling system with coolant. To prevent air pockets, refill coolant with return hose removed.
Start engine. Allow engine to run until engine thermostat opens, purging air from cooling system. Engine must be run to eliminate air from heating system before energizing heater.

WIRING

Connect heater to an appropriately rated power source. Ensure power source is grounded and in accordance with local and national electrical codes. If necessary, install control box:
- If your heater is single-phase and rated up to 480 volts, your heater may be powered directly without the use of a control relay or contactor.
- If your heater is three-phase or is single-phase and rated for over 480 volts, the heater thermostats must be used in a control circuit with a contactor for switching the main power to the heating elements.

RETURN PORT

- - Select a return port away from the engine thermostat.
  - Select a return port high on the engine.
  - Select a return port toward the rear of the engine.
  - Select a return port away from the remote thermostat. NOTE: If an optional remote thermostat is installed
  - Select a return port away from the supply port.

SUPPLY PORT

- - - Select a supply port low on the engine.
    - Select a supply port toward the front of the engine.
    - Select a supply port away from the return port.

HEATER MOUNTING

Mount the heater in the proper orientation. Ensure heater outlet faces upward.
Mount the heater to a vibration-isolated surface.
Mount the heater directly below the return port.
Mount the heater at least 6 inches (15 cm) below the lowest point of the water jacket.

LUBE OIL AND INDUSTRIAL IMMERSION HEATERS

Oil Heaters

Oil Heaters up to 277 V AC meet recognized CSA standards for safety or performance.

To specify temperature range of thermostat, insert code from

chart in place of the XX in model number.

Example:

Desired Temp. Range 80 °–100 °F Model Number: OW2121XX-000 Order as: OW212108-000

Temperature Range ON OFF				Code
60 °F	(16 °C)	80 °F	(27 °C)	06

100 °F	(38 °C)	120 °F	(49 °C)	10

See p.25 for remote thermostat assembly part numbers.

Oil heater with Y-cord and remote thermostat

DC Oil Heaters

Use a thermostat with all lube oil heaters to protect the oil from overheating. Lube oil heaters must always be installed in the sump with the entire heater submerged below the oil level at all times. See page 25 for remote thermostat part numbers.

*NOTE: If heating gear oil (medium weight viscosity), HOTSTART recommends using low watt density heaters.

See wiring schematic page 35

All HOTSTART heaters with thermostat, operating on three phase current (at any voltage), require the use of a control system with a 3-pole contactor. All HOTSTART heaters with thermostat, operating over 480 V (single or three phase) require a control system to reduce the primary voltage to 120 V for the control circuit. For increased thermostat life, use a control system on all heaters above 277 V either single or three phase.

All control boxes can be used with either single or three phase heaters.

Control boxes are available in Hazardous Location models - contact factory for part number.

For heater protection and power savings, HOTSTART recommends de-energizing the heater when engine is running. Control boxes are supplied with a 24 V relay to de-energize the heater upon engine start-up.

To prevent overheating of the heating element on standby equipment and automatic start engines, HOTSTART recommends turning

the coolant heater off when the engine is running. A pressure switch that senses engine oil pressure is utilized to shut the heater off on increase of oil pressure and to turn the heater on when engine oil pressure drops.

Specifying an

Determine the best type of heater to be used for the application.
- In-block or Thermosiphon Engine Heater?

Engine Heater

Weathertight model for all indoor or outdoor applications (hospital, communications

building, shopping mall, pump station, off-road equipment).

- Hazardous Location model (off-shore platform, oil rig, gas compression station).

Determine engine size.
- Cubic inch or liter displacement.
Determine wattage required by using this general formula:
- 3 watts x cubic inch displacement = watts required.

Example: Engine is 855 CID. Requirement is 2500 watt heater. (855 x 3 = 2565)

- This formula is a very good rule of thumb to use down to 0 °F (-18 °C) ambient temperature. This formula will generally hold engine temperature at approximately 100 °F (38 °C) above ambient.
- Engines over 1250 CID (20 L) and V-type engines require forced circulation preheating systems (CTM, CSM models — see pages 4-5).

Now that you have the required wattage, you need to determine:
- Voltage available that will power the heater (120, 208, 277, 240, 380, 480).
- Is the power source Single Phase or Three Phase?
For thermostat selection, determine the desired engine temperature to be maintained.
- 100 °F (38 °C) to 120 °F (49 °C) applies 95% of the time. However, specifications vary with respect to the user and a higher or lower range may be required.

You now have the specifications needed to select the required engine preheater from the many products listed in this catalog. For other technical information and installation tips, see pages 22 and 51. If you have other questions or need additional assistance, please contact our customer service department.
