WICU® Clim

Pipe for air conditioning unit

Manufacturer Serravalle Copper Tubes

WICU® Clim


Air conditioning
Refrigerant gas transportation.

This copper tube is manufactured according to EN 12735-1 and is pre-insulated in closed cell expanded polyethylene where the cells are of regular size and evenly distributed (compliant to EN 14114). It is distributed in coils. The copper tube diameter is expressed in inches, as required by standard EN 12735-1. The insulation sheath is manufactured in full compliance with European Regulation EEC/EU 2037/2000 that enforces the use of insulating expanded foam sheaths devoid of CFCs and HCFCs which are harmful to health and the environment. The thickness of the sheath is designed to satisfy the various requirements of this application area. Given the particular application field, special attention is reserved for the external protective polyethylene film designed to prevent the formation of condensation on the outer wall of the product.
WICU® Clim is also characterised by an extremely low eccentricity values, a very important feature for flaring operations.

Further details

Internal surface
The inner surface of the copper tube is bright, clean and dry, essential characteristics of this product category normally available on the market for industrial use. This particularity allows for the achievement of an integrated system with the terminal units of the plant. The particular internal factory cleanliness of WICU® Clim material is safeguarded by fitting terminal sealing stoppers at production.
External protection
Polyethylene closed cell expanded foam with average water vapour diffusion resistance factor “μ” equal to 10000. The insulating sheath is manufactured under full compliance to European Regulation EEC/EU 2037/2000 which enforces the use of expanded foam insulation sheaths devoid of CFCs and HCFCs which are harmful to health and the environment and have class 1 fire resistance compliant to Italian Min. Decree 26/06/84.
The outer polyethylene film has a darker pigment than the traditional white to counter the PE crystallisation process. In addition, normal anti-UV additives tend to degrade the flame retardant treatment necessary for the product. In order to avoid this drawback, the WICU ® Clim sheath contains an environmentally friendly halogen-free flame retardant that does not counteract the anti-UV action.
Tests conducted according to ASTM G-155 (accelerated ageing) confirm that WICU ® Clim is suitable for areas with high annual solar radiation. At the end of the exposure test, the sample did not show any signs of degradation (see photo).
