Hamilton Storage Verso^® Q20

Natural refrigerant with GWP 3 and zero ozone depletion potential.

500 W variable cooling capacity with a refrigerant charge of only 80 g.

Base concept with minimal temperature fluctuations and noise emissions.

Less than 100g of refrigerant!

I appreciate that ThermodynamX has developed a solution using natural refrigerants. This makes our product future-proof and is a major advantage for our customers.

The situation

Hamilton Storage offers flexible solutions for storing laboratory samples under defined environmental conditions. Their automated systems are among the best in the international market in terms of performance, user-friendliness, and ease of use. Hamilton Storage wanted to expand its product range with an extremely compact product that would fit in any laboratory yet offer the full performance of an automated sample storage system. ThermodynamX was responsible for the cooling from the outset.

The challenge

For the successful implementation of the new plant, we had to consider, among other things, the following criteria:

Use of exclusively natural refrigerants

Base-based design (high serviceability)
A cooling unit filled with refrigerant must be able to be shipped by air freight.
Wide range of applications: Storage temperature from -20 °C to +20 °C
Multi-voltage: 110 V / 60 Hz to 230 V / 50 Hz connection

Technical and regulatory guidelines, coupled with high customer demands, often result in very demanding requirements. Thanks to a methodical approach and close collaboration with our customer, we implemented these requirements step by step and verified them with measurements.

The result

The cooling unit for the Verso Q20 product was developed. As requested, the cooling unit is located in the base and docked to the chamber from below. A major advantage for servicing: In case of a defect, the entire cooling unit can be replaced in under 15 minutes. Furthermore, the base design allowed for a hermetically sealed refrigeration circuit. This enables the cooling unit to be installed in the field without a refrigeration technician – essentially plug and play. And: Unlike other units, air freight is permitted because the refrigerant charge in the circuit is less than 100 g – made possible by a compact design and optimized components. Thanks to the variable-speed control of the compressor and fan, the cooling unit operates efficiently and very quietly.

Verso Q20 proves itself on the market

Hamilton Storage is adding the Verso Q20 product to its range of storage platforms. It was first presented at SLAS in San Diego at the end of January 2020. The natural refrigerant, with an ozone depletion potential of zero and a global warming potential of three (GWP 3), proves to be a more environmentally friendly alternative compared to deep-freeze systems using conventional refrigerants.

We are delighted for our customer and thank them for the excellent collaboration.
