Confremar Put the new IceDry®30 Through it's Paces!

Confremar SA in Madrid manufactures and distributes frozen products. The company's lines include: frozen fish, shellfish, pre-cooked products and vegetables.
Confremar also hire cold storage to other frozen product companies so it is very important for them to provide cold storage with the very best conditions. The relationship between Confremar and Munters began in 2005 when they decided to improve their installations. The first part of the project was the installation of three Munters units for three new cold stores: one ML17 blows air in two doors and two ML1350's were supplied for the other two.
Since installation Confremar has kept the cold stores free of ice and frost, they have avoided fog formation and slippery floors, plus increased the refrigeration efficiency and reduced energy consumption Thanks to these excellent results, Confremar turned to Munters again and installed four more units for a new cold storage area with chambers of different sizes.
Munters installed two MX5000's blowing dry air into twelve cold store chambers, an MX5000 for six chambers and one MX6200 blowing air into seven old chambers to eliminate the ice formed on the walls and ceilings, so ensuring good conditions for workers. All these Munters units have been equipped with Munters MX energy recovery kits to reduce energy consumption.
Results have been excellent for Confremar. The MX range dehumidifiers were designed over ten years ago. With an effective sealing system and desiccant rotor which make it still the most effective desiccant dehumidifier on the market. Munters have since developed an upgrade kit which makes this unit even more effective. Energy reductions up to 25% can be made, without the unit losing its capacity.
INTERNAL ENERGY RECOVERY
Use of traditional external heat recovery systems has always been an available option for these types of dehumidifiers. Normally this would require considerable investment and a lot of extra space around the dehumidifier.
But now Munters has an internal energy recovery upgrade kit which can easily be retrofitted to the existing installation. The extra space required is minimal. This upgrade kit reuses the residual heat in the desiccant rotor, so that the required regeneration heat is less. The results in a lower energy consumption at the same dry air output. Alternatively this residual heat can also be used to make the air more dry (lower dew point) at the same energy cost. Munters is the world leader in humidity control, and by developing this upgrade kit have shown again that Munters care about their customers, even if they bought equipment ten years ago.
Because the heat in re-used in the system, the dry air leaves the unit at a lower temperature. Contrary to some other external heat recovery systems, the Munters MX Energy recovery system does not require any frost protection when outside air is used. The investment of the retrofit usually pays back within one year. The retrofit doesn't require any change in the existing ducting and can be installed within a day, including an efficiency check of the system.
After the retrofit no extra periodical maintenance is needed. The standard scheduled maintenance activity will suffice. Confremar are very happy with the solution and trust Munters fully, as Munters have given them the right solution in every case. Confremar are testing the new IceDry30 in a cold store with ice problems.
