Technical Applications for Liebherr in Australia
In Australian clinical and research environments, maintaining precise temperature control is vital for the long-term stability of vaccines, chemicals, and biological specimens. The range of Laboratory and scientific equipment from this brand includes specialised General purpose refrigerators or refrigerator freezers that offer uniform temperature distribution through forced-air cooling. These units are often paired with Measuring and observing and testing instruments, including high-accuracy Laboratory freezer or refrigerator thermometers, to provide secondary verification of internal storage conditions.
For facilities handling volatile or flammable substances, the spark-free laboratory refrigerators and freezers provide a critical safety layer. These units are certified under the ATEX directive, ensuring that the interior chamber is free from potential ignition sources while storing combustible materials. By integrating advanced alarm systems and remote monitoring capabilities, we help Australian laboratories mitigate risk and ensure the continuous safety of their valuable inventories.
Why Source Liebherr from John Morris Group?
- Profi and Comfort Controllers: These precision electronic systems allow for temperature settings to 1/10 degree accuracy, featuring integrated data memory and 3-point calibration for superior documentation.
- Innovative Hot Gas Defrost: Featured in LKPv, LGPv, and LGv models, this technology enables extremely short defrost cycles that maintain internal temperature stability without compromising the integrity of stored contents.
- Certified Spark-Free Safety: ATEX-certified interiors allow for the safe storage of explosive or highly flammable substances, making these refrigerators ideal for chemical and pharmaceutical research.
- Exceptional Energy Efficiency: Utilising environmentally friendly refrigerants like R 600a and R 290 combined with thick insulation, these units significantly reduce energy consumption and global warming potential.
- Superior Build Quality: German-engineered with chrome-nickel steel liners and antimicrobial handles, these appliances are built for a 15-year service life in demanding professional environments.
We back this precision range with 70 years of local expertise, providing Liebherr customers with factory-trained service, NATA-Accredited Calibration support, and dedicated technical guidance.
Frequently Asked Questions
What is the difference between Profi and Comfort electronic controllers?
Profi controllers are designed for high-capacity applications and include a real-time clock, enhanced data logging, and advanced calibration options. Comfort controllers provide reliable digital temperature control and alarm functions suitable for standard laboratory and medical storage requirements.
How does the hot gas defrost cycle preserve temperature-sensitive samples?
Unlike traditional heaters, the hot gas system reverses the refrigeration cycle for a very short duration to clear frost. This process is much faster and generates significantly less heat, ensuring that the internal temperature remains almost constant and the samples are never exposed to damaging warmth.
What are the benefits of an ATEX-certified spark-free interior?
An ATEX-certified interior is engineered to eliminate any electrical or mechanical components that could cause a spark. This allows for the secure storage of flammable liquids or volatile chemicals in partially open containers without the risk of an internal explosion.
Are these refrigerators suitable for the storage of sensitive vaccines?
Yes, many models are specifically designed to meet the stability and consistency standards required for vaccine and medicine storage. Features such as forced-air cooling and the +2 degree SafetyDevice protect these sensitive biologicals from accidental freezing or overheating.
Can Liebherr units be connected to a remote monitoring system?
Most laboratory models are equipped with a volt-free alarm contact and an RS 485 interface, allowing them to be integrated into building management systems. This ensures that any temperature deviations or power failures are immediately reported to the relevant control centre for action.
Does John Morris Group provide local maintenance for these systems in Australia?
We offer full local support across Australia and New Zealand, including installation, preventative maintenance, and repair by factory-trained technicians. Our team also provides NATA-Accredited Calibration to help you maintain compliance with strict laboratory and clinical quality standards.
