ISECO trolleys at La Gourmande

Carbo-Fresh System

  • Carbo-Fresh injection station including control panel, time controlled injection gun, exhaust system and CO2 security
  • One push easy to use buttons with preset timers

Food transport lorry at La Gourmande

A lorry arrives and takes its position at the loading zone. The lorry is ambient and NOT refrigerated - resulting in huge cost savings. Loading of the trolleys is easy and comfortable [3 abreast with maximum 10 in a row]. Average time between loading and unloading at site is 45 minutes.

The lorry returns with empty/used meal trolleys. Removal of transport security bars takes place. Trolleys are unloaded to the cleansing zone.

Automatic Monitoring

  • Return of the used trolleys to the ’unclean’ zone adjacent to the wash-up area
  • Isecom system transmits a ’wake-up call’ to the trolleys modem and identification takes place
  • The alerted modus is activated and all data is transferred

Trolleys arrive in wash-up/cleaning area where another transmitter collects all data from the trolleys [in random order] and transfers the data automatically to the nearby office. A computer records and saves all the data. Any malfunctions, misuse or temperature problems being reported and highlighted on screen, including identification of trolleys and destinations.
