kyCubic Line/Single Air Dischargeky General Contents

General FeaturesMost of our unit coolers are available in the following versions:

• Direct expansion evaporators

• Brine unit coolers

• Pump ammonia evaporators

Certifications and reliability All DX u nit coolers are guaranteed by Eurovent "Certify All". Alfa

Laval quality systems fully comply with ISO 9001, and all of our

products are manufactured in strict accordance with CE regulations.

Fin spacingIn our experience, fin spacing should correspond to both the goods

stored and the room’s air temperature, as follows:

Series Green Line Red Line B lue Line

Product Fruit /Vegetables

Meat / Fish Frozen food

Room temperature 10 ÷ 0°C 0 ÷ -7°C -18 ÷ -25°C

Fin spacing 3 ÷ 4,5mm 5 ÷ 6mm ≥ 7-12mm

CapacityThe standard conditions are in accordance with EN 328. The cooling

capacities stated in the catalogue are the nominal capacities for

Qn (wet conditions), in compliance with Eurovent regulations. In

standard Qst conditions (dry), the nominal capacities are calculatedwith the following formula:

Qn = Qst x Wet Coil Factor

Relative humidity ΔTThe cold room hygrometric conditions are defined by the room

temperature and the working ΔT. At positive cold room temperatures

ΔT has an influence on the relative humidity (RH).

Air throw

Air throw (L)=air velocity limit 0.25m/s.

The values given in the tables are based on an air temperature of

20°C beneath a flat ceiling with no obstructions. The height and

air circulation of the room can influence the air throw. The stated

distances are based on a final air velocity of 0.25m/s.

FansSingle-phase motors 230V-50Hz, or three phase 400V-50Hz,

protection class IP54 according to DIN 40050. Integrate thermal

protection by thermo contact. Provide reliable protection against

thermal overload.

Defrost All our coolers come equipped with several different defrosting

systems. For room temperatures where ice build-up is likely, and

where the ambient room temperature is below 0°C, a unit with a

defrosting system is needed

Test and cleaningThe coils are cleaned and dehydrated in order to remove any traces of oil. Each heat exchanger undergoes a pressure and leak test with dry

air at 34 bar, before being supplied with a nitrogen pre-charge.

Guarantee All our products are protected under warranty for 24 months from the factory shipping date. In the unlikely event o f a defect occurring within

the warranty period, please return the equipment or faulty part free of charge to us, where we will decide whether to repair or replace the

goods . Unfortunately, We cannot take responsibility for damage caused by the misuse or incorrect installation of our products. Brochure

Local safety switch and cabling for each electric fan motor.

Plastic covering box, IP66, nominal current 16A – 3 phases, insulated voltage 600V.

Reference and standard CE/UL/CSA. Per unit.


All Models

Fan ring heater FRH)

Application:

To prevent the freezing up of the fan blades at the collar in extremely humid conditions during

defrost in cooling or freezing rooms.

Supply conditions:

Electric heater with stainless steel shell, stainless steel fixing spring and connection box.

Model:ALL

APPLICATIONS

All Models

Air sock adapter ring

Ø

Applications: Flower, fruit and vegetable storage areas, supermarkets, ba keries, slaughter houses

and other meat-processing operations. Price per unit cooler.

Benefits: Equal cooling effect without draught, even temperature distribution, com fort in cold working

areas.

The sock reduces the airflow and capacity. Please contact Alfa Laval for design and unit section.

Model:

Casework component in stainless steel AISI 304.

Application Use: More information on corrosion prevention can be found in the Miscellaneous section.


All Models

Insulated drip tray

Construction: Sandwich manufactured with two aluminium shells and 12mm of polyethylene

insulation in between.

Features: The insulation prevents water condensing on the bottom side of the drip-tray and reduces

the transfer of the defrost heat into the cold room. It can be combined with Electrical or Hot Gas

defrost.

Applications: Room tem peratures below -25°C and foo d processing rooms.


All Models

Cable electric heater

Applications:

We recommend that you heat the drain pipeline while defrosting to prevent ice forming in the pipes.

The flexible electric heater can easily be placed inside the pipe.

Power: 70W.

Voltage: 230V


All Models

Reheating coil

Use:

It’s an additional coil used for dehumidifying or heating the air outlet of the evaporator. It can be

one or two rows deep. There are two systems:

- using warm water with a minimal flow rate providing small air temperature rise.

- Using electric heaters fixed into the finned tube coil.

Quick selection:

• Product available: AlfaCubic Dx, Ammonia.

• Permanent 2 row tube for reheating coil.

• Coil sizes with reheating water:

• A (cooling size) + 2 rows (reheating coil)

• B (cooling size) + 2 rows (reheating coil)

• In case C coil size: due to space limitations in the unit, the cooling coil will be B with + 2

rows for reheating

-

Model:DX/Ammonia

All Models, exceptØ 500

Coil Treatment / Material

Pre-coated fins: Epoxy-coated, pre-painted aluminium fins.

Cataphoresis treatment: An electrolytic process is achieved by submerging the coil in a paint bath,

where it acts as a cathode and gets completely coated in an epoxy paint, which gives exceptional

protection against corrosion. Recommended for alkaline or salty atmospheres.

Stainless steel tubes with aluminium fins: The coil is available in stainless steel tubes with aluminium

fins.

Application Use: More information on corrosion prevention can be found in the Miscellaneous section.
