Question 1

How long does it take to install a cold room?

Accepted Answer

The installation duration of a cold room depends on several factors: size, type (refrigeration or freezing), location, installation complexity and availability of prepared utilities.

Approximate duration:
• Small, modular rooms (2–10 m²) → 1–2 days
• Medium rooms (10–30 m²) → 2–4 days
• Large / industrial rooms → 5–10 days or more
• Complex cold storage facilities → can take several weeks

What influences the duration: space preparation (flooring, ventilation, electrical installation), type of refrigeration unit (monoblock or split), need for additional automation and testing and commissioning.

In general, for a standard cold room, the actual installation is relatively quick, but the total time can increase if preparatory work or special adaptations are needed.

Question 2

What temperatures can cold rooms reach?

Accepted Answer

Cold rooms can reach different temperatures depending on their purpose and construction type.

Usual temperature ranges:
• Refrigeration chambers: between 0°C and +8°C (for fresh meat, dairy, vegetables, beverages)
• Freezing chambers: between -18°C and -25°C (for frozen products)
• Deep freezing chambers: between -30°C and -40°C (used in the food industry or laboratories)
• Special / industrial chambers: can reach up to -60°C in special applications

What influences the temperature: refrigeration unit power, panel insulation level, chamber volume and outdoor ambient temperature.

In conclusion, cold rooms can operate from positive refrigeration temperatures to very low deep freezing temperatures, depending on the application requirements.

Question 3

How much does an air conditioning system consume? Can it be used in winter?

Accepted Answer

The consumption of an air conditioning system depends on the unit's power, energy efficiency, operating duration and usage conditions.

Approximate consumption by capacity:
• 9,000 BTU (≈ 2.5 kW) → 0.7 – 0.9 kWh/hour
• 12,000 BTU (≈ 3.5 kW) → 0.9 – 1.2 kWh/hour
• 18,000 BTU (≈ 5 kW) → 1.5 – 2 kWh/hour
• 24,000 BTU (≈ 7 kW) → 2 – 2.5 kWh/hour

Values are for normal operating conditions; inverter technology can reduce consumption after reaching the set temperature.

What influences consumption: energy class (A++, A+++), inverter technology, space insulation, set temperature, room size and outdoor temperature.

Yes, an air conditioning system can be used in winter if it has a heating function. The unit reverses the refrigeration cycle and works as an air-to-air heat pump. Standard models work down to approximately -5°C / -10°C, high-performance models down to -15°C / -20°C. Air conditioning is an efficient heating solution in winter, especially in areas where temperatures do not frequently drop below -15°C.

Question 4

What refrigerant do you use for air conditioning systems?

Accepted Answer

For air conditioning systems, different types of refrigerants are used, depending on the appliance technology and environmental regulations.

Most commonly used refrigerants:

• R-410A – Used in most modern split and multi-split units. Does not affect the ozone layer (ODP = 0). Higher working pressure. GWP: 2088.

• R-32 – More energy-efficient refrigerant. Reduced impact on global warming (GWP: 675, lower than R-410A). Also without ozone depletion effect.

• R-134a – Used less frequently in small units, mainly in older systems. Does not affect the ozone layer, but has a high GWP (1430).

• R-407C – Replacement for R-22 in some applications, compatible with older systems. GWP: 1774.

R-32 and R-410A are the current standard for new units, combining efficiency and environmental compliance. R-134a is found more in older or industrial equipment.

Question 5

How often should refrigeration equipment maintenance be performed?

Accepted Answer

The frequency of refrigeration equipment maintenance depends on the type of equipment, usage intensity and manufacturer recommendations.

Recommended intervals:
• Cold rooms / large freezers – General check, condenser and evaporator cleaning, refrigerant control → every 3–6 months
• Commercial display cases – Filter and glass cleaning, temperature check, door sealing → monthly
• Air conditioning / heat pump systems – Filter cleaning, pressure check, outdoor unit inspection → every 6 months
• Industrial refrigeration equipment – Complete control and adjustments, compressor and automation check → quarterly or semi-annually

Additional checks: temperature and energy consumption monitoring (continuous or periodic), immediate intervention if alarms or performance drops occur, replacement of worn parts according to manufacturer recommendations.

Regular preventive maintenance prevents breakdowns, extends equipment lifespan and maintains energy efficiency. For critical equipment (industrial or medical), some checks may be monthly or even weekly.

Question 6

Do you offer service contracts with rapid intervention?

Accepted Answer

Yes, we can also offer service contracts with rapid intervention. These ensure priority and very short response times, but it should be noted that the rate is higher compared to standard contracts, due to the increased level of availability and promptness offered.

Question 7

What happens if the equipment breaks down outside working hours?

Accepted Answer

In case the equipment breaks down outside working hours, we are notified at the contact number for such urgent situations. Each contract includes a specific rate for interventions outside working hours. We intervene as quickly as possible when the problem requires rapid action or provide advice on measures that can be taken until the actual intervention, if the situation allows postponement.

Our goal is to solve the problem in a way that is advantageous for both parties, without unnecessarily burdening the client's bill, but also without jeopardizing goods or equipment.

Since problems can arise at any time, it is ideal to have a contract. The contractual relationship offers the advantage of a faster and priority response to clients with whom we work constantly.
