Ultra-low deep freezer or ULT Freezer is critically important in the life sciences, laboratories and pharmaceutical industry.  It is used for long-term preservation of samples at precise temperatures.Since the lifespan of an ultra low freezer is around ten to fifteen years, it gives better value for money. Thus, buying a good-quality freezer is a good decision.There has been a tremendous advancement in the freezing technology in the past three decades. Modern freezers are much more effective and efficient than the earlier times.Since Available model as per space constraints., e.g. upright freezers, chest freezers and so on, users can select the best suitable model.

Benefits of using ultra freezer

1. Energy Efficiency

Earlier, high power consumption was an inhibiting factor, but improved technology makes ULT freezer quite energy efficient today. Hence, you get savings on energy bills. Because of the concerns with carbon footprint, innovative low temperature freezers are available. These freezers use liquid nitrogen for cooling which remains liquid for extended periods. Since no compressor is used here, the energy consumption is considerably low. Thus, you get a better return on investment.

2. Low Sound

Modern low temperature refrigerators are available with sound reduction system. There are easy-to-access front vents with filters that reduce noise up to a great extent. Also, the freezers have balcony vents on the back side to lower down the noise further. Thus, you get ultimate thermal efficiency without increasing the decibel count. Before purchasing one for the freezer room, read the technical specs thoroughly.

3. Tailor-made Solutions

When you go through the laboratory footprint, you realize that the off-the-shelf product doesn’t suit your needs. There is nothing to worry.  Cold room manufacturers in Mumbai can offer customized solutions matching to your requirements. Whether it is the number of compartments or configuration of the door, in-built voltage stabilizer or compressor settings; you can get it designed conveniently.

4. Excellent temperature control

The most important feature of an ultra low deep freezer is that it offers amazing control over the temperature. It has robust inner doors, highly efficient gaskets and quicker pull-down and recovery times. Hence, they are ideal for applications that need uniform temperatures consistently.

5. Sustainability

When you buy high-standard freezers, you get transparency for power consumption, recyclability, service life and manufacturing quality. Therefore, it makes sense in buying a reliable ultra low deep freezer for your business. The money you spend gives great returns in the long run.

How Much Does it Cost to Run an Ultra-Low freezer?

The upright mechanical or ‘minus 80’ freezer is one of the most commonly used types of storage freezer. Frequently referred to as a ‘ULT’ or an ‘ultra-low freezer’, they are similar in design to household freezers. They normally utilise a refrigerant like propane (R290) or ethane (R170) to function and are powered by motors or compressors.

A fixed temperature of -20 °C or -40 °C can be maintained by a standard upright mechanical freezer, but the majority will run at approximately -80 °C. Mechanical freezers can maintain lower temperatures than this, but it can cause significant strain on the motor and may result in failures.

To maintain temperatures as low as this, a consistent power supply is necessary. Phil Wirdzek, the President and Executive Director of the International Institute for Sustainable Laboratories, explained that the traditional ULT freezer utilises approximately 20 kWh of energy per day, the same amount of energy as a single-family home.

The energy and running costs can quickly add up, considering that research facilities and laboratories normally run dozens, if not hundreds, of these freezers at once.

An upright, mechanical ULT freezer can vary in average running costs from £570 ($750) to £750 ($1000) each year according to a number of factors. Frequent upkeep and maintenance through defrosting can decrease this expense, but not significantly.

These prices do not account for the extra expense of the removal of warm air and HVAC systems. This can increase the cost even more and is a serious consideration for storage facilities and laboratories that have a limited budget. A significant environmental impact is also caused by constant energy usage.

Factors to be considered while purchasing Ultra low deep freezers

There are several factors that need to be considered while purchasing Ultra-Low Deep Freezer to fulfill the requirement of different applications. The buyer must always look for various provisions whether they are provided with the machine or not such as:

  • Communication port,
  • Data logger or data storage,
  • Proper provision of alarm that can be triggers when the temperature reaches the set point,
  • Door open or door closure provision,
  • Temperature uniformity or temperature recovery options.

High-end and premium quality of deep freezers helps to maintain uniform temperature inside the chamber and quickly recovers the same once the door is closed after opening. When the door is opened, warm air of outside environment enters the freezer that causes the device to work harder for a period of time to maintain the set temperature and to condense or freeze water vapor in the chamber itself. The speed at which the freezer maintains temperature jaunts is a function of high-end compressors that reserve the capacity according to the thermostat and maintain the cold temperature all across the cabinet even in the presence of heat load.
