36 Cold Stores All cold, no ice
FOG AND ICE, frosting up of evaporator coils, reduced efficiencies and overworked refrigeration plant – these are all familiar issues to any cold store operator. Indeed, they are so familiar that they are often simply accepted as part and parcel of running a cold store.
After all, a cold store has to have a low temperature, so things are sure to get iced up – or are they?
There is now a positive course of action you can now take to tackle these problems at their source.
Due to the difference in water content in the ambient air and the air in the cold store, problems with ice and frost
accelerate when moisture- loaded outdoor air enters the cold store.
Kitchen Range Foods supply products to big brands food outlets as well
as wholesalers, and this was put in potential jeopardy when the company suffered from the biggest challenge they had faced – humidity. According to Andy Gordon, engineering manager at Kitchen Range, the company had tried many other options over the years, from drop down plastic curtains at the lower end of the market, through to an air curtain at the upper end, with varying degrees of success.
Eventually, Kitchen Range contacted Munters who installed an IceDry desiccant dehumidifier inside the cold store in order to target moisture at the source. The result, says Mr Gordon is that “the condition of the cold store has greatly improved and we are now snow and ice free for the first time in many years. “We no longer have issues with refrigeration equipment icing, blocking up and the cold store is now the best it’s even been for excessive ice and snow build up on the walls and packaging.”
According to the company, IceDry is the only dehumidifier that has been developed especially for installation inside a cold store. The environment demands new and special features created with the sole purpose of ensuring that the unit runs reliably and energy efficiently. Installation is simple. IceDry is positioned close to a wall and needs only a few metres of ducting around it. Reactivation air is taken from the room next to the cold store.
