Inquiry about Ultra-Low Temperature Freezer with CO₂ Backup and Chiller System NEW

We are sourcing laboratory equipment for an R&D project in Portugal. We require an ultra-low temperature freezer operating at approximately -80°C/-86°C, vertical or compact configuration, with a storage capacity of around 7 litres or above. The unit must include digital temperature control and display, high/low temperature alarms, power failure alarm, data logging or temperature monitoring output, and remote alarm contact if available. It should be suitable for biological and molecular research samples, 230 V / 50 Hz, CE compliant. We are also interested in a compatible CO₂ emergency backup system capable of maintaining ultra-low temperatures during power or refrigeration system failure, including all components for installation and operation. If the proposed freezer requires or can benefit from an external hydronic heat-exchange or chiller system, please quote the appropriate system separately. If not required, please confirm explicitly. We are open to the smallest and most cost-effective model that meets the above specifications, including demonstration units, showroom units, or end-of-line models with appropriate warranty and documentation. Please provide your best project price, including delivery to Madeira, Portugal.
