GENERATOR, FIRE PUMP & WASTE PUMP - BLOCK HEATERS:

Maintain Oil Viscosity & Cold Starting Performance.

Engine block heaters, also known as water jacket heaters or engine pre-heaters, are normally supplied and installed as a generator package accessory. For some generator models, this could be a factory-installed accessory, and for others, it may be an optional price-adder that the customer can choose at the time of purchase. Block heaters are typically used in environments where any stationary engine is subject to ambient temperatures below 16 degrees celsius. They add reliability to the system by preheating the water jacket coolant of the engine and maintaining a warm temperature, thus assisting the engine start cycle for rapid on-load performance, assist to achieve faster oil pressure, provide overspeed prevention due to cold engine overfuelling, improved oil delivery and enhance general engine protection.

Can't find parts for your existing block heater?
Replacement parts cost more than a new heater?
Can't adjust the temperature?
It's fried itself electrically?
Plastic junk casing is cracked and leaking?
Die cast alloy casing has become corroded, porous and is leaking?
Your hoses don't fit correctly?
WE CAN HELP, DOZENS OF SUPER SATISFIED CUSTOMERS WORLDWIDE?

• 100% New Zealand designed & built.
• Precision TIG welded, LASER cut components.
• 304 grade stainless steel.
• Ideal for generators, fire pumps, water pumps, waste pumps, marine applications or any stationary engines.
• Can be retro fitted to any engine of any size. Larger "V" engines may require one on either side.
• Lasts a lifetime, no more plastic or die cast alloy junk.
• Accepts various hose tail sizes (supplied with kit).
• All hose tail threads are ^3/4" BSP.
• Universal, pre drilled mounting kit (supplied with kit).
• Can be horizontally or vertically mounted (electrical terminal box must be at the top for vertical installation).
• Can be installed with or without a circulating pump.
• Comes with 1500W (standard), 2000W or 3000W Incoloy element. Titanium available on request.
• Double check your wiring and fuse/breaker sizes to ensure your load can be supported.
• Comes with 20A resettable (standard) or non-resettable Thermostat.
• Simple to install single phase 230V.
• All electrical components are NZ compliant and conform to AS/NZS standards.
• Replacement thermostats and elements available from any electrical wholesaler.
• Easy temperature control, no more cooked cylinder heads, water pumps and hoses.
• We recommend genuine, made in USA, Continental Blue Xtreme (available from Blackwoods in NZ) heater hose and not the cheap half rubber, half chalk, rubbish. Dunlop have a similar product. Some customers have reported good success with silicon hose. Quality hose costs a lot more but lasts a lifetime.
• Prevent potential heater explosions and only install isolation valves on the engine side, and never on the heater body.
• We suggest all engine side hose tails and valves are stainless steel or good quality brass or nickle plated brass.
• The larger the pipework, the better the circulation.
• Use a small quantity of nickle based anti-seize with a minimum of 12 wraps of PTFE based thread tape to insert fittings correctly. Add thread glue if you have.
• We recommend a block temperature of 35-40 degrees (max) Celcius, remembering that the actual heater temperature will be much higher.
• Don't boil the block, head gaskets and water pumps will simply start leaking.
• Thermosyphon requires a reasonable height difference between inlet and outlet on the engine side for it to work correctly. The larger the height difference, the better it works. For greater efficiency, connect the high side of the heater to the high side of the engine and similarly on the low side. Don't plumb anything through the thermostat assembly, and ensure design flow even when the engine is in a cold (thermostat closed) state.
• Diagonal flow across the engine is best, one hot inlet on the back of the head and one cold outlet diagonally lower down works best.
• Hoses must not have kinks or droops, direct from the heater to the respective engine connection point is best.
• Block heater must be flooded and bled before powering up. Easiest method is to connect coolant hoses, open isolation valves and run engine for a few minutes. Top up coolant once installation is complete.
