A refrigeration specialist has spoken out in opposition to the observe of “topping up” merchandising machines with damaging Flourocarbons as a handy guide a rough repair selection to repairing environmentally destructive leaks.
DGB refrigeration’s Gary Barlow says: “Topping up frustrates me and I think it is something we all should be very concerned about. It is illegal and has grave consequences for the environment.”
As the time period suggests ‘topping up’ is the addition of refrigerant to a chiller which has a recognized leak, or the evaporator has develop into porous.
Vending machines are predominantly gassed on R134A – a Fluorocarbon which when launched into the ambience at once contributes to the rise in world warming. Every 1kg of carbon dioxide equals a GWP (world warming doable) of one in line with kg, while R134A has a GWP of one,300 in line with kg.
“As an instance, a leak of simply 1kg of this refrigerant reasons the similar environmental injury as using a van for 10,000 miles.
“Without in fact repairing the leak/evaporator, the chiller will want power topping up that could be handy as a handy guide a rough repair however will imply extra engineer name outs, down time of the gadget and misplaced inventory.
“At DGB Refrigeration all repairs are done in our purpose built factory which enables us to pressure test chillers for leaks, but also we have brand new evaporators made for the units with a history of this problem – once a evaporator has become porous it is virtually impossible to repair.”
