Looking to reduce energy consumption on freezer usage while at the same time increasing capacity? In response to a strong demand from protein customers for refrigeration solutions that meet both requirements while at the same time offering more direct control, JBT’s LVS Refrigeration™ System now offers a solution which can be retrofitted on almost all existing Frigoscandia freezers.
JBT understands the need to reduce energy consumption and save energy, and with this in mind has engineered the LVS Refrigeration System for low energy consumption and optimum freezer performance. However, the benefits of the LVS don’t only end there: the system offers substantial economic advantages, with the chance to reduce your refrigerant charge by up to 50%.
“With an LVS, you can reduce energy consumption and increase freezer capacity, which are linked together,” explains JBT Refrigerant Development Engineer Håkan Ohlsson. “You also have a reduced ammonia charge, as well as more direct control over the system.”
By having the separation of liquid and gas done close to the freezer – and not far away as in a traditional pump system – typical production capacity losses are only total 0.5% compared with between 3-5% for a pump system, says Ohlsson. “Every degree C loss is equivalent to 3% loss in freezer performance, so it’s a huge difference,” he adds.
In fact, JBT LVS Refrigeration units are up to 20% more efficient than traditional pumped refrigerant systems with a patented dry suction system that delivers more capacity from the compressor and enhanced evaporator performance; all adding up to greater freezer capacity.
Another significant advantage offered by the LVS is its ability to deliver an enhanced sustainability performance compared with most traditional systems. Although additional safety equipment and training is required, JBT recommends the use of ammonia with the system; a neutral gas, which has zero global heating impact. However, even in instances where CO2 is used, the LVS enables customers to reduce the charge and thus the overall environmental impact.
Retrofitting is another important feature available through the LVS, with the system designed so that almost any JBT Frigoscandia freezer can be converted. The principal benefits of the LVS, continues Ohlsson, can be summed up as reduced losses and charges, savings of space in the engine room and reduced energy consumption, plus the option of connecting additional compressors directly to the system. “Through valve control, we can control the refrigeration both for cooling, defrosting and drying, so the freezer performs as well as possible,” he says.
“It is an obvious thing for JBT to help customers improve their sustainability, and therefore development of our LVS system is important – and clearly outlined – in the JBT strategy,” Ohlsson concludes.
