PUF INSULATED PANELS - Srikanth Enterprises

Blue Star’s Deep Freezers are the most effective and economical for safe storage of perishable foods. The range of Hard-top Deep Freezers from Blue Star incorporate cutting-edge technology and innovative feature, guaranteeing long-lasting freshness. Built to last and to meet the demands of the high sub-continental temperatures, these machines cut power bills through energy -saving innovations thus, helping your business grow.

Blue Star also ensures that every new solution it brings to the marketplace is eco-friendly and green, and contributes to a sustainable future of reduced global warming and zero ozone depletion. The introduction of the eco-friendly R410a refrigerant in most of its airconditioning solutions, for example, goes a long way in helping the country meet its obligations to reduce the use of HFCs under the Montreal Protocol.

The company now introduces eco-friendly pre-fabricated insulation panel systems in a range of profiles, thicknesses, and finishes. The speciality of these panels is that, they are perfect for the speedy creation of cold stores of any size at the site due to their precise interlocking design and great insulation properties, and are also eco-friendly both in their material and in their manufacturing process itself.These new eco-friendly panel solutions from Blue Star can be used to create cold storages of any
size, from small walk-ins to very large cold rooms.

A cold storage is a critical piece of infrastructure for any industry. The quality of stored produce and raw material depend upon the reliable and precise functioning of the cold storage.

Blue Star’s experience in creating cold storages that offer different storage conditions in terms of temperature, humidity, fresh air, air flow, etc., to suit different industry requirements has made them the leaders in this domain too.

The company’s engineers plan and design cold rooms based on advanced heat load calculations using internationally acclaimed softwares thus building your desired cold room with precision.

Blue Star’s Cold Storage Division’s domain expertise extends across a wide spectrum of industries that includes:

Agro Industry

Cold Chains

Dairy

Floriculture

Food Processing

Healthcare

Horticulture

Ice Cream

R & D Labs

Sea Food

Panels

Blue Star’s new range of pre-fabricated insulation panel systems are easy-to-use interlocking panels that can be used to create cold rooms of any size at the site.

Since the insulation material in these panels is foamed between two metal skins, they offer highly effective insulation for cold rooms.

What’s more, these panels are designed to ensure precision interlocking and hence they form leak-free walls ideal for cold rooms.

Manufactured in a wide range of profiles, thicknesses and finishes, these systems can be used to create cold stores at the site and of any size — from small walk-ins to very large cold rooms.

Doors

Blue Star offers a complete range of insulated doors to complement its world-class
environment-friendly PUF panels.

The polyurethane foam insulation sandwiched between GI sheets makes the doors perfect for high-performance cold rooms.

Self-closing: Ensures that the door remains closed without any human interaction
Safety release: Doors can be opened from inside
View port: Helps view products stored inside without opening the door, which is not just for convenience but for power saving too.
Posi Seal: Provides perfect alignment of frames and ensures perfect closing movement
Sweep gasket: Air-tight heavy-duty sealing gasket below the door remains flexible at any temperature
Thermal break: Eliminates thermal conductivity which otherwise leads to condensation and ice formation

Panel Systems

Blue Star’s new range of pre-fabricated insulation panels are eco-friendly from the ground-up since even the manufacturing process is green.

Cyclopentane: The eco-friendly blowing agent

Cyclopentane is increasingly becoming an industry standard the world over as an eco-friendly blowing agent. Blue Star has also invested in using cyclopentane as the blowing agent in the manufacture of its new series of insulation panels. This makes the panels ‘green’ even in their manufacturing process, and further underlines Blue Star’s commitment to a greener tomorrow.

This ensures zero Ozone Depleting Potential (ODP) and reduces Global Warming Potential (GWP) as compared to the more generally used HCFC-1415 which is not environment friendly.

Why cyclopentane

ODP (Ozone depletion potential): 0
GWP (Global Warming Potential): Negligible (11)
Complies with TUV standards, CCOE (India) certification

Blue Star’s commitment to a healthy environment is thus further reinforced by this investment in a cyclopentane process, which not only ensures superior yet environmentally friendly products, but also supports India’s obligations under the Montreal Protocol on ‘Substances that Deplete the Ozone Layer’.

Cyclopentane vs Conventional HCFC-141b:

S.N	Particulars	HCFC 141b	Cyclopentance
1	11	GWP (Global-warming potential)	630
2	ODP (Ozone-Depletion Potential)	0.11	0
3	Fire retardant property	Self-extinguishing	Self-extinguishing

Facilities aiming to become green buildings will find these panels ideal for their LEED certification process.

Each Blue Star pre-fab insulation panel has cam-action locking devices precisely positioned and firmly anchored within it. All cam-locks have integral rear flanges to permanently anchor their position during the manufacture of the PUF panels. Cam-locks are also placed at exact matching locations on the tongue and groove side to ensure perfect locking.
