What is an EPS insulation and what is its purpose in VRF systems?

EPS (Expanded Polystyrene) is a closed-cell rigid foam, foamboard insulation, which is characterized by superior thermal resistance and lightweight characteristics. In VRF systems, insulating refrigerant branch junctions are required, to ensure undesirable heat transfer, to remove condensation to reinforce energy efficiency, which has a direct impact on lowering operating expenses and indirectly increases the system life.

What is the comparison of DA Series EPS insulation unto the standard XLPE insulation?

EPS insulation is usually cheaper in k-value (thermal conductivity) as compared to conventional XLPE, and has better insulating properties. This has a very high thermal gain or loss through the piping and helps the refrigerant to stay at a very accurate temperature thus improving overall system efficiency, reduces energy use, and offers improved condensation control.

Do you offer EPS insulation for VRV/VRF branch piping applications?

Yes. 227 Enterprise provides EPS insulation designed to enhance thermal efficiency and prevent condensation in VRV/VRF branch piping systems. The insulation helps maintain stable refrigerant temperatures, reduces energy loss, and supports long-term system reliability when installed as per project and environmental requirements.

What are the main advantages of your designed-insulation EPS?

We have our own specially designed EPS insulations which are pre-shaped to the exact shapes of the Y-joint to ensure a perfect fit. This helps seal all air gaps or thermal bridges and provides the system with the maximum thermal efficiency, eliminates condensation, and makes the installation of the system easy and treats it with a clean and professional finish that works throughout the lifespan of the system.

What is the method of installation of the EPS insulation on the Y-joint?

Its insulation has user friendly, pre-slitted or clam-shaped design which can be easily wrapped around the complex geometry of the joint. This strongly clamp type does not need special tools and bonding chemicals to be fastened there and thus can be installed very fast and without errors on-site that would save precious labor time and provide uniform, gap-free insulation cover.

What are the quality and safety requirements of your products?

Our products come under strict test and joints under pressure testing of up to 5.2 MPa. The EPS insulation is also fire-resistant, compliant with ASTM E84 on low flame spread and smoke density, and also RoHS and CE compliant, which means that they are highly consistent in terms of safety, environmental responsibility, and performance with high International standards.

How long is the lead time of orders?

For customized specifications or bulk orders, we provide a specific timeline after reviewing your detailed requirements. We prioritize open communication and will work with your project's critical path to establish a mutually agreeable schedule that meets your installation deadlines.

How long is the lead time of orders?

In the case of a conventional DA Series item, we normally have a 7-10 day dispatch lead time. In case of customized or bulk orders, we will give you a particular timeline after you present your detailed requirements and we will maintain a communication line with this and a good schedule to match your project critical path and deadlines of setups.

Does it provide warranty support on the DA Series with EPS insulation?

Yes, we do offer a full warranty on materials and workmanship on the DA Series. We can ensure that the copper joints and EPS insulation will be defect free and will meet intended performance in the typical conditions of operation with our warranty that will be supported by our quality and customer services.

What is the relationship between energy saved in a VRF system with the use of EPS insulation?

With the minimization of thermal transfer, EPS insulation helps in reducing the workload of the system to cover the heat gain/loss. This reduces the compressor energy requirements by a large margin increasing the Coefficient of Performance (COP). The outcome will be an immediate decrease in the electricity consumption and operational expenses which will provide a high payoff on the investment over the lifespan of the system.
