Snugger’s SS4200 is primarily used to pre-heat engines allowing for easy starts in cold weather climate. It can also provide a level of comfort heat when plumbed through an onboard heater exchanger. The coolant heaters are operated with a simple ON/OFF switch or an optional programmable timer.
When added to the onboard water circuit, cold engine starts are eliminated because the unit will tap directly into your vehicle’s fuel supply and battery system. Snugger offers both an 4 & 5 kilowatt coolant heaters that have the ability of increasing coolant and thus increasing engine block temperature significantly in less than an hour. This allows for an engine start similar to that of a summer’s day.
