HOC has launched a new refrigeration system aimed specifically at multi-drop delivery vehicles.
Called Transcool, it utilises liquid nitrogen to combat the temperature rises caused by the frequent door opening on such vehicles.
With the system, short injections of liquid nitrogen at minus 196° C into the body interior keep the air temperature down. This provides a very rapid cooling effect to counteract the opening of the vehicle door without overcooling the load.
These injections can be automatically or manually controlled. In the automatic ,system, called Econocool, a ,thermostat operates the spray iat a preset temperature while with the manual version the driver presses a button in the cab, giving a timed burst of between one and five minutes after deliveries.
With both versions, if the vehicle is left loaded overnight, liquid nitrogen is automatically injected.
The 75 or 150-litre nitrogen container can be mounted either inside or under the vehicle.
One major food distribution company is already using the Transcool system as one of its depots and is converting more of its fleet. Its drivers also like the new system, as th vehicles no longer need I noisy overcab refrigerati motor, making them lighter steer, more stable and quiet Further details are avilal from Tony Watts, BOC L Hammersmith House, Lond W6 9DX.
