Otelsan Absorption System Minibars: Eco-Friendly, Energy-Efficient and Cost-Effective Solutions for Hotels

In today’s hospitality industry, guest comfort and satisfaction are just as important as reducing operational costs. Otelsan Absorption System Minibars are designed to meet both needs by offering an environmentally friendly, energy-efficient minibar solution for hotels. Thanks to advanced absorption cooling technology, these minibars significantly reduce energy consumption while ensuring reliable storage for beverages and snacks.

What Is an Absorption Cooling System?

An absorption cooling system differs fundamentally from conventional compressor-based refrigeration. Instead of relying on mechanical compressors, absorption minibars operate using a thermo-chemical process involving ammonia, water, and hydrogen. Heat—rather than electricity—is the primary driving force of the cooling cycle.

This technology allows absorption minibars to operate with extremely low electricity consumption, making them an ideal solution for hotels seeking sustainable and energy-saving equipment. Additionally, the absence of moving mechanical parts ensures silent operation, a critical advantage for hotel room environments.
