Understanding Heat Load

Reefervan guarantee installation packages will always exceed expectations and customer requirements for both quality and cooling performance.  


Reefervan take time to explain all the factors that can affect the cooling capacity & ask appropriate questions when selecting the right reefer and insulation for your vehicle. We make sure your Reefervan products perform to your requirements.


Excessive external heat affects the operational performance, therefore we thermally balance the reefer & insulation based on information gathered from customer.  Not correctly "balanced" your Reefer may not cool effectively during transportation!

  • Reefervan Reefer Equipment and Insulation Products cool approx. *2°F (1°C) every two minutes of operation

  • Excessive External Heat / Door Openings / Insulation Thickness all can effect Product Temperature 

  • Pre-cooling the cargo area will maintain the correct temperature

  • Use of Optional Standby Electric / Shore power is recommended to cool van when stationary

     (* Based on ambient temperature and relative humidity, figures may change)

Good Reefer Operation Practice - TIPS & HINTS 


  • Pre-chill the cargo area for 15 minutes before loading on very hot days.

  • Switch the reefer unit off while loading product into cargo area.

  • Minimize the length of time that doors are open when delivering.

  • Product should be stored at the correct temperature before loading.

  • Do not block the evaporator air intake or outlets.


  • Allow space around all sides of the cargo load for air circulation.

  • Check the load temperature before loading and regularly on route.

  • Using standby power, check that the mains power supply is suitably rated to power the reefer unit (Min 20A).

  • Switch the vehicle engine off and cab control off before connecting mains power.

  • Avoid using additional extension leads on electric standby. Maximum length of cable is 25 feet.
