FAQ Your Comprehensive Guide to Maintenance & Fault Questions in Refrigeration and Freezing Systems
I. Comparing Refrigeration Systems
What is the fundamental difference between cold rooms and freezer rooms?
The choice depends on the type of product stored, room size, frequency of door opening, and outdoor climate conditions in Saudi Arabia.
How do I choose the right system for my cold storage warehouse?
The difference lies in temperature ranges: cold rooms operate between +1°C to +5°C for fresh products, while freezer rooms operate below -18°C for frozen products.
II. Faults & Technical Solutions
What are the most common causes of filter dryer damage?
It balances the pressure inside the room when temperatures change, preventing difficulty opening doors or structural damage to the unit.
Why does the cold room temperature suddenly rise?
The main cause is the accumulation of moisture or impurities in the refrigeration cycle, leading to blockage of refrigerant flow and additional pressure on the compressor.
How do I know if the Expansion Valve needs replacing?
The cause is often a refrigerant gas leak, a faulty expansion valve, or a blocked evaporator unit.

What is the role of a Pressure Relief Valve?
When you notice ice accumulation on the evaporator or unstable temperatures inside the room despite the compressor running continuously.

III. Maintenance & Operation in Saudi Arabia
What is the most suitable PU insulation thickness for warehouses in Saudi Arabia?
Due to the extreme heat, we recommend a minimum thickness of 100mm for cooling and 150mm for freezing to ensure energy efficiency.
How often should preventive maintenance be performed?
Ensure the integrity of the insulating gaskets and keep doors tightly closed to minimize warm air infiltration.
Does dust affect the efficiency of refrigeration units?
We recommend preventive maintenance at least every 3 months to ensure condenser cleanliness and compressor efficiency.
What are the best practices for maintaining cold room doors?
Yes, dust accumulation on condensers reduces heat exchange efficiency, leading to increased electricity consumption and compressor damage.

IV. General & Commercial Questions
Do you provide medical refrigeration solutions (hospitals)?
The cost depends on insulation efficiency, compressor type, and set temperature. At Hassounah Refrigeration (HRC), we design systems to be the most energy-efficient.
What is the monthly operating cost of a large cold room?
Yes, we provide precise temperature control systems dedicated to medical facilities to ensure the safety of medicines and vaccines.
Can cold rooms be installed in small restaurants?
By equipping the system with phone-connected alarm devices and backup systems (UPS) or emergency power generators.
How do I protect goods in the event of a power outage?
Absolutely. We offer compact Modular Room designs suited for limited spaces in commercial kitchens.
Do you offer installation services across all regions of Saudi Arabia?
Yes, our technical team covers all regions of the Kingdom for certified installation and maintenance services.
What does the term "Friga Bohn " mean?
It is a distinguished international brand in refrigeration evaporators. We work with their latest technologies to ensure high performance.
Why are Copeland compressors considered the best?
We provide detailed technical reports after each maintenance visit, outlining the condition of units and
faults that have been repaired.
How do I request a technical consultation for a new project?
They are distinguished by high reliability, spare parts availability, and their ability to withstand harsh operating conditions in the Saudi climate.
Do you provide original spare parts?
You can contact us via WhatsApp or visit our headquarters, and we will study your project requirements and provide an appropriate technical offer.
How is maintenance documented?
Yes, we are committed to supplying original spare parts that comply with international specifications to
ensure system continuity.
How do I choose the right cold room capacity for my project?
Capacity depends on the type of goods, quantity, and frequency of door opening. At HRC, we visit your site and accurately calculate thermal loads to ensure the ideal capacity that neither wastes energy nor increases costs.
How much does it cost to build a cold room for a restaurant or warehouse?
The cost varies based on the area, insulation thickness, and type of refrigeration unit. We provide customized solutions that fit your budget — contact us directly for an accurate quote.
Do cold rooms consume a lot of electricity? How can I reduce costs?
Consumption depends on insulation efficiency and compressor power. We use energy-saving refrigeration systems with high-quality thermal insulation to minimize electricity bills.
How long does cold room installation take?
We adhere to a precise schedule from design to final commissioning. We aim to deliver fast, professional service to get your business running as soon as possible.
Do you provide periodic maintenance after installation?
Yes. We don't just sell equipment — we build long-term relationships. We offer periodic maintenance contracts to ensure your business never stops.
What is the difference between a standard cold room and a freezer room?
Standard cooling preserves fresh products (e.g. vegetables) at above-zero temperatures, while freezing preserves products (e.g. meat) at below-zero temperatures. We help you choose the best system for your goods.

Do you offer custom designs for small spaces?
Yes, all our projects come with a warranty on both equipment and workmanship for your peace of mind.
Do you provide a warranty on equipment and installation?
Absolutely. We specialize in optimizing space usage, whether in a compact restaurant or a large warehouse.
How do I ensure the quality of room insulation?
We use certified insulation materials suited to the Saudi climate to maintain temperature stability and prevent heat leakage.
Can the room be expanded in the future?
We design our rooms with a flexible system that allows future expansion if your project grows and storage needs increase.
V. Technical Questions
Why do you use Copeland compressors in your projects?
Because Copeland compressors are the global standard for quality and reliability.
Why are BOCK units considered a strong choice in refrigeration?
BOCK units are extremely powerful German units that withstand the harshest operating conditions — ideal for large projects requiring continuous performance.
What is the importance of a control panel in a cold room?
The control panel is the "brain" of the room — it regulates temperature and protects the compressor from electrical fluctuations, extending the system's lifespan.
Do you supply evaporators from international brands?
Yes, we work with the best manufacturers worldwide.
