Energy saving. Reliable. Productive. Cost effective.

CAPEX will cover you for years to come

The system can be divided into infrastructure and copper plates alongside GPU's. One of our most important advantages is that the entire engineering infrastructure of the product can work and serve you for as long as 15 years (with regular maintenance). Thus, our system is most effective for long-term capital investments. In case an upgrade to the GPU cards is needed, simply change the copper cooling component. The infrastructure can remain in service for many generations of GPU's.

Liquid cooling allows all GPUs and CPUs to work in the normal temperature range, so the system will serve you well for a long time to come. That’s why Comino offers a one-year warranty on its devices — under normal conditions of use and service — which is four times more than that of most air-cooled solutions. Notice also that under ‘normal conditions’ we mean the system operating at full power in 24/7 mode.

No noise

The fanless system built around plate heat exchangers is not only effective, but almost completely silent.

Easy upgrade

Whenever you want to upgrade the system, just replace the GPU blade — and continue to use the rest of the infrastructure, avoiding any additional expenses.

Heat recovery

The heat generated can be reused for other purposes, such as space or water heating.

Simple maintenance

Comino Grando is designed around quick disconnect couplings and modular approach, providing you easy access to any node in the system and significantly reducing modernization costs.

Low power consumption

Low power consumption compared to traditional air cooling. Comino Grando spends less energy on maintaining the system's temperature, effectively reducing your electricity costs.

Сooling system

The cooling system allows Comino Grando to operate safely in any climate, at any time of the year.


The software is designed for remote monitoring and diagnostics of the entire system.

* Variation of ±7% Mh/s is expected. Hashrate depends on the hashrate of the network and can be changed after particular blockchain software changes. Comino doesn't guaranty the hashrate rate it does guaranty its hardware stability only. There are financial risks associated with mining cryptocurrencies. These risks can be related to changes in exchange rate of the cryptocurrency or to changes in the algorithm that is used to mine the cryptocurrency. Please deliberate well before making a purchase because we will not accept any requests for refund for orders.
