New Tool - Diesel Engine Block Heater Monitor

The Cure for Cold Weather Starting for Diesel Engines

New patent pending electronic device, Power-Block(TM), monitors block heaters to prevent freeze ups

CEDAR RAPIDS, Iowa - A new invention from JoSa Enterprises promises to reduce or eliminate cold weather starting problems for commercial vehicles or fleets with diesel engines.

This revolutionary new tool designed for the trucking industry and school buses is the Power-Block(TM). It is a patent pending device that monitors truck block heaters during the cold weather months, saving valuable time, energy and resources by keeping trucks on-the-road and safe from cold-weather freeze-ups.

Commercial trucks or busses with diesel engines are all equipped with a heater whether it be a coolant block heater, fuel tank heater, battery heater, or oil pan heater. Any or all of these can be used in the winter to help the engine start. If no heater is used and if it is cold enough, the engine will not start. If any of these heaters are used but something is wrong with them, it could not be detected until the truck would attempt to be started the following day. This is where the Power-Block comes into play. And, it retails for $199.95. Every truck or bus should have one to prevent winter fuel freeze-ups.

The Power-Block will immediately tell the operator, 1) the AC voltage coming out of the cord; 2) the heater's efficiency; and 3) if the block heater is functioning properly. This is all vitally important information in keeping your truck on-the-road and making you money during the cold winter weather months. These simple units of measurement are Volts, Watts, and Amps on a simple display. Just plug in the Power-Block, see the LED display light up and walk away knowing your block heater is working.

The Power-Block will also benefit any service locations that work on equipment. During their preventative maintenance schedules, the technician can check the performance of the trucks heater whether it be an engine block heater, oil pan heater, battery heater, fuel heater, hydraulic tank heater, etc.

The Power-Block was built to NEMA 4 standards, which means the unit is waterproof, weatherproof, and shockproof. This high performance unit was designed to withstand the harsh elements of winter and function consistently. The Power-Block is also a fail-safe device, meaning that in the rare event the device malfunctions, the unit will act as a cord, keeping electricity flowing through the device and the block heater working.
