HEAT EXCHANGER

CHS – Compact Hitec Surface - TURBOFIN® 3 heat exchanger

The heat exchanger with internally grooved tubes and staggered rows, suitable for both positive and negative temperature applications for the conservation of products with low humidity content, or packed products.

LHS – Large Hitec Surface - TURBOFIN® 4 heat exchanger

The heat exchanger with internally grooved tubes and in-line rows, featuring a high ratio between the secondary fin surface and the primary tube surface, suitable for conservation cold rooms for products with high humidity content, and for freezing.

HEAT EXCHANGER

The superefficient Turbocoil® 2 and Turbocoil® 3 heat exchangers, featuring the highest obtainable ratio of capacity/cost are constructed with:

• High efficiency small-diameter copper tubes with internal helicoidal grooving designed for the new refrigerant fluids. 
• High efficiency aluminium fins (TURBOFIN®2 and TURBOFIN®3) with specially configured turbulator profile to reduce dehumidification and the formation of frost.

DEFROST OPTIONS

N = air defrost (TC> 2°C) 
E = electric defrost (TC> -35°C) 
G = hot gas defrost for coil and electric defrost in the drain tray (TC> -35°C)

FEATURES

• New directional JETSTREAMER^® grill which ensures uniform air flow distribution across the heat exchanger
• Available with the LU-VE patented distributor JET-O-MATIC^®
• Available with Nidea® - New intelligent Defrosting Apparatus

EMERITUS® is the latest innovation developed for the range of condensers, dry coolers and CO2 gas coolers manufactured by LU-VE Exchangers.

• CO2, NH3, HC, Glycol, HFC, HFO
• From 4 to 22 EC fans
• 3 different configurations
• Available with Whisperer plus ® silencer, designed and tested in the LU-VE laboratories, that dramatically reduces sound pressure level up to -6 dB(A).
   

ADVANTAGES:

• CAPACITY: +400% compared to traditional dry-operation exchangers
• BETTER COP: reduction of DT1
• SILENT OPERATION: up to -6 DB(A) reduction of sound level
• ELECTRICAL ENERGY SAVINGS: up to 60%
• SPACE SAVINGS: up to 80% footprint reduction
• REDUCED WATER CONSUMPTION: up to 95% less compared to traditional cooling towers
• AUTOMATIC WATER-QUALITY CHECK: equipped with sensors to constantly check water quality
• PROTECTION: fins are made of a new magnesium-aluminium alloy coated with a special paint treatment (ALUPLUS®) to guarantee strong protection against corrosion.
• INTELLIGENT CONTROL SYSTEM: with innovative, user-friendly functions. In addition to controlling electronic fans (EC), its sophisticated software memorizes the total operating hours of each ramp of the spray circuit and each adiabatic panel. Thanks to a "logic of rotation", it selects which system should be activated, optimizing the numbers of hours per year of spray operation.
• This new technological advance (patent pending) is the result of collaboration with POLITECNICO DI MILANO and brings together the benefits of spray systems and adiabatic pre-cooling. A sophisticated control system maximizes the effects of these combined systems.

• CO2, NH3, HC, Glycol, HFC, HFO
• Wide range from 40 to over 1000 kW
• From 1 to 8 EC or AC fans
• Low noise operation and reduced energy consumption.

The XDHV and XDHL ranges exploit the latest advances in technology, already successfully applied to the most recently developed LU-VE products.

FEATURES

• Available with Whisperer plus ® silencer, designed and tested in the LU-VE laboratories, that dramatically reduces sound pressure level up to -6 dB(A).
• Available in AS (Adiabatic System) configuration

• CO2, NH3, HC, HFC, HFO
• 4 sizes from 10 to 250 kW
• From 1 to 4 EC-fans
• Low noise operation and reduced energy consumption.

MINICHANNEL® has been designed for reducing refrigerant charge and energy consumption, combined with high operating pressures.

Heat exchanger with special configuration of fins with “louvre” cuts which are positioned very closely together, capable of optimizing and increasing heat transfer performance, thanks also to the use of special high-efficiency tubes with internal grooves.

ADVANTAGES:

• Very high level of solution flexibility
• Very wide range of tube-fin configuration (and consequent elimination of over-sizing for standard products)
• Unlimited range of possible applications. The same technology is applicable to condensers, evaporators, reversible heat exchangers (heat pumps), multi-circuit and cross flows, exchangers with different refrigerants (water and HFCs).
• Reduced weight (less copper, therefore reduced raw material costs) compared to traditional tube-fin solutions.
• Can be serviced and repaired on-site.
