evaporators_image2
 
General information & application
Alfa Laval Optigo is a new platform for commercial air cooler ranges. Forming a common 'DNA', this platform offers a newly developed and highly efficient coil block and many other features. The Optigo CS is a commercial air cooler for general application in small to medium-sized cooling and freezing rooms. The model's design is characterised by a low silhouette (only 15 cm for CS20) for the efficient use of cold room space. Optigo CS coolers are available from stock.
 
Evaporating temp. +10 to -30°C
Refrigerants all H(C)FC, brine and CO2
Capacities (SC2) 652 up to 7808 W
Air volume 517 up to 4262 m3/h
 
Coil
Innovative coil manufactured from internally grooved Cu tubes ø 5/16” (smooth tubing for brine applications) and aluminium fins. Tube pitch 30x26 mm staggered. Standard fin spacings 4 and 7 mm.

Casing
Durable aluminium casing, white epoxy coated RAL 9003. CS30 removable plastic side panels for easy access. Hinged drip tray construction. Separated fan sections. The CS20 model is suitable for top connection and is also available with a drip tray for wall mounting.

Fan motors
Standard fitted with state-of-the-art dual fan speed EC motors in two diameters (200 & 300 mm), blowing through the coil. Fans pre-wired to the connection box. Power supply is 230/1/50-60. Enclosed design spray-tight fan motors, protection class IP-54.

Easy installation
Easy installation and maintenance thanks to hinged drip tray construction and removable side panels (CS30). Delivery with dismounted side panels in cardboard shipping box. Mounting mould available inside box.

Certifications
All DX cooler models are “Eurovent Certify All” certified.
The Alfa Laval quality system is in accordance with ISO 9001.
All products are manufactured according to CE and PED regulations.

Design pressure
Design pressure 33 bar (H(C)FC, model CSE), 6 bar (brine, model CSW) or 80 bar (CO2, model CSX). Higher design pressures on request. Each heat exchanger is leak tested with dry air and finally supplied with a nitrogen pre-charge. Options

• Electric defrost (E), mounted as default for 7 mm, optional as a separate kit for 4 mm models.
• Coil corrosion protection
- epoxy coated aluminium fins (EP)
- cataphoresis treatment (CA)
• Wall mounting, CS20 only (WM)

Selection
Selection and pricing is to be performed with our Alfa Laval air heat exchanger selection software. Selection output includes all relevant technical data and dimensional drawings. Please contact our sales organization for details and full technical documentation.
