XB Refrigeration Co., Ltd. is a professional Cold room installation company in Thailand. We compare the performance of Cold room foaming agents, help you select suitable Cold room insulation foaming agents, optimize insulation layers and reduce Cold room energy consumption.
Polyurethane insulation layers for Cold room are mainly formed with foaming agents. Various foaming agents are divided into physical foaming agents and chemical foaming agents according to their chemical properties. Physical foaming agents form bubbles through vaporization and expansion, while chemical foaming agents generate gas via chemical reactions. The table below compares key properties of common foaming agents:
Foaming Agent Type | Thermal Conductivity (W/m·K) | Environmental Performance | Cost | Application Scenario |
HCFC-141b | Approx. 0.021 | Moderate, phasing out | Low | General Cold room |
Cyclopentane | Approx. 0.024 | Eco-friendly | Medium | Food & export Cold room |
HFO-1233zd | Approx. 0.018 | Eco-friendly, low GWP | High | High-efficiency energy-saving Cold room |
Water-blown | Approx. 0.028 | Eco-friendly | Low | General applications with moderate insulation requirements |
HCFC-141b used to be a widely adopted foaming agent with stable foaming performance and low cost, once the mainstream option among various foaming agents. However, it is being phased out globally. Using it for long-term projects will bring regulatory and supply risks. Its thermal conductivity is at a medium level and provides limited help for overall Cold room energy saving. Therefore, XB Refrigeration Co., Ltd. recommends evaluating eco-friendly alternative foaming agents for new Cold room projects.
Cyclopentane is an eco-friendly physical foaming agent without ozone depletion potential, and it stands out for cost-performance among various foaming agents. The insulation layer formed by cyclopentane features high closed-cell ratio and favorable thermal conductivity, suitable for food and export Cold room. It should be noted that cyclopentane is flammable. On-site ventilation and explosion-proof measures are required during construction, and operations must be carried out by professional teams.
HFO-1233zd is a new-generation eco-friendly foaming agent with extremely low global warming potential (GWP). Its thermal conductivity is excellent among various foaming agents. With this foaming agent, the insulation layer delivers better thermal performance at the same thickness and reduces cold loss. It is especially suitable for high-end Cold room with strict energy-saving requirements. Although its cost is relatively high, it brings substantial long-term electricity savings.
The selection of proper foaming agents requires comprehensive consideration of Cold room usage, temperature requirements and budget. The table below provides material selection suggestions for typical Cold room projects in Thailand:
Cold room Type | Recommended Foaming Agent | Suggested Insulation Thickness | Expected Energy Saving Effect |
Large Freezer | HFO-1233zd | 150–200 mm | 15%–25% reduction in electricity cost |
Food Chiller | Cyclopentane | 100–150 mm | 10%–18% reduction in electricity cost |
Budget Cold room | Water-blown / HCFC-141b | 80–120 mm | 5%–10% reduction in electricity cost |
Reasonable selection of various foaming agents lays the foundation for Cold room insulation and energy saving. In response to Thailand’s hot and humid climate and actual Cold room operation demands, XB Refrigeration Co., Ltd. conducts integrated design covering foaming agent types, insulation thickness and construction techniques. Investing in proper foaming agent selection at the initial stage can greatly lower Cold room electricity bills, reduce equipment load, extend the service life of the whole Cold room system and create stable benefits for customers in Thailand.
A: Yes. Different foaming agents can lead to over 30% difference in insulation performance. Proper selection can cut Cold room power consumption by 10%-25%.
A: The upfront procurement cost is slightly higher, yet long-term energy savings are greater. It also avoids environmental regulatory risks for better overall economics.
A: Yes. Cyclopentane and similar foaming agents are flammable and require professional explosion-proof work. XB Refrigeration Co., Ltd. implements standard construction to guarantee safety and quality.
