Refrigerator: Performance and service at high temperatures

When should we use a refrigerator?

There are situations where hydraulic equipment has adverse temperature environmental conditions . This can happen in shopping centres, hospitals, exhibition centres or in areas with very high temperatures.

In these cases, where hydraulic equipment has a high traffic (many daily journeys), the fluid's temperature can rise excessively and cause the elevator to stop, leaving it out of service.

To prevent this heating of the fluid, the cooler is responsible for keeping it at a constant temperature , thereby allowing for an increase in the number of starts per hour. Consequently, the hydraulic equipment can work without forcing the elements and therefore, the useful life of the entire assembly is increased .

Which refrigerator to choose according to the installation of an elevator

GMV has several types of refrigerator depending on the circumstances of the installation:

Cooling kit for installations with ventilation

• Ideal for installations in high traffic and high temperature conditions.
• Increase in the number of starts/hour.
• Extends engine life and oil quality.
• Recommended for public buildings, offices and hospitals.

Cooling kit for indoor installations

• Independent of ambient temperature.
• Use of refrigerant gas
• Smaller dimensions
• Lower sound level
• Recommended for indoor premises.

Cooling kit in facilities with distance between machine room and ventilation point

• Ideal for installations in high traffic and high temperature conditions.
• Increase in the number of starts/hour.
• Extends engine life and oil quality.
• Recommended for buildings with distance between the machine room and the ventilation point.

The useful life of a hydraulic lift was previously estimated at around 20 years. Today, with proper maintenance and the use of this type of components that optimise the operation of the hydraulic equipment, its durability can be increased to 30 years.
