Long Term SupportIf a laboratory freezer stops working, it can put critical biological samples, vaccines, and research materials at risk. The first step is to check the power supply, ensuring the freezer is plugged in and the circuit breaker hasn’t tripped. If the issue persists, transferring samples to a backup freezer or dry ice storage can help maintain ultra-low temperatures. Many modern laboratory freezers feature temperature alarms and remote monitoring systems, alerting users to potential failures. Regular maintenance, temperature monitoring, and having a contingency plan in place are essential to prevent sample loss and ensure the reliability of laboratory cold storage.
No, chest freezers use less energy than upright freezers, making them the more energy-efficient option. Chest freezers have a tighter door seal and more consistent internal temperatures since they lack a self-defrost system, reducing energy consumption. On average, an ENERGY STAR® certified chest freezer uses about 215 kWh per year, costing around $30 annually to run, while an upright freezer uses approximately 395 kWh per year, costing around $50 annually. This significant difference makes chest freezers a better choice for energy efficiency, helping to lower electricity costs while maintaining optimal storage conditions.
Yes, chest freezers generally last longer than upright freezers due to their simpler design and better temperature retention. On average, a chest freezer can last between 12 to 20 years, while an upright freezer typically lasts around 10 to 15 years. Chest freezers have fewer mechanical components, reducing the risk of breakdowns, and their tighter door seal helps maintain stable temperatures, reducing strain on the compressor. Additionally, they are more energy efficient as cold air stays inside when the lid is opened. With proper maintenance and defrosting, chest freezers offer longer durability and reliability compared to upright models.
It is generally better to keep a freezer full rather than empty. A well-stocked freezer maintains a more stable temperature as the stored materials help retain the cold and reduce temperature fluctuations when the door is opened. This is especially crucial for biomedical samples, vaccines, and biological materials, where even slight temperature changes can affect viability. However, freezers should not be overpacked, as proper airflow is essential for consistent cooling efficiency. If a freezer is not fully stocked, using thermal ballast such as water bottles can help maintain temperature stability and improve energy efficiency.
The ULUF ULT series has the lowest power consumption on the market, making it an energy-efficient choice for ultra-low temperature storage. Designed for sustainability, this freezer series reduces operational costs while maintaining stable ultra-low temperatures. It utilises natural refrigerants with a low Global Warming Potential (GWP), ensuring eco-friendly performance without compromising reliability. If you’re looking for a low-energy freezer that delivers efficiency and sustainability, the ULUF ULT series is a top choice for laboratories, medical facilities, and research institutions.
Yes, freezers tend to use more electricity as they get older due to factors like wear and tear on components, reduced insulation efficiency, and declining compressor performance. Over time, an ageing freezer may struggle to maintain its set temperature, causing it to work harder and consume more energy. Poorly sealed doors, frost buildup, and dirty condenser coils can also contribute to increased electricity usage. Regular maintenance, defrosting, and cleaning can help improve efficiency, but if your freezer is over 10–15 years old, upgrading to a newer, energy-efficient model could significantly reduce energy consumption and running costs.
Our freezers are manufactured in Denmark, Poland, Italy, China, and Korea, ensuring high-quality production standards across multiple locations. Each facility follows strict quality control and engineering excellence to produce reliable and energy-efficient freezers for various industries.
The life expectancy of a chest freezer is typically around 16 years on average, although they can last anywhere from 12 to 20 years depending on various factors. Chest freezers, like refrigerators and electric ranges, are some of the longest-lasting kitchen appliances. However, this lifespan is not guaranteed and can be influenced by factors such as proper maintenance, usage, and environmental conditions. By following best practices for freezer care, including regular defrosting, checking seals, and ensuring the right temperature settings, you can help extend the lifespan of your chest freezer, ensuring it stays reliable for many years.
Chest freezers typically need to be defrosted once a year, or when the ice buildup reaches about a quarter of an inch thick. As chest freezers do not have an automatic defrost cycle, they require manual defrosting on a regular basis. Regular defrosting is essential to maintain the freezer’s efficiency, as excess frost can obstruct airflow, increase energy consumption, and impact cooling performance. By defrosting annually or when frost buildup occurs, and by checking the seals and temperature settings, you can ensure your freezer operates optimally, extending its lifespan and improving energy efficiency.
