Güntner V - SHAPE Compact  – Powerful and smart

The units of the newly developed V - SHAPE Compact family are available as fluid cooler, condenser and gas cooler and offer maximum capacity on a remarkably small footprint already when operated in dry mode. The o ptional HydroPad humidification pad for adiabatic pre - cooling allows for operating refrigerating plants more efficiently, thereby saving money – no water treatment, no intense maintenance works and no wetting of the coil required. The available Güntner Hyd ro Management GHM pad decides continuously whether applying water or increasing the fan speed is more cost - effective.

The V - SHAPE Compact cooler: In a class of its own

The new V - SHAPE Compact units round off the product portfolio of the V - SHAPE familie s at the lower end with regard to capacity. Each heat exchanger is specifically designed for the fluid HFC, CO 2 or water/glycol mixture.  The  core  tube  diameters  and  materials,  in  combination  with  the  fin  geometries,  provide  the  best possible combination of maximum capacity and minimum tube volume. Operated with the optional adiabatic HydroPad pre - cooling system and the wide range of accessories, the V - SHAPE Compact leaves nothing to be desired in its performance category.

Adiabatic HydroPad pre - cooling sys tem: One system, many benefits

The optional adiabatic HydroPad pre - cooling system offers substantial savings. On the one hand, the wetting system  can  increase  the  capacity  of  the  unit  allowing  you  to  operate  smaller  units  with  a  reduced  footprint without u ndermining the given capacity requirements. And on the other hand, this option allows for operating all  the  refrigerating  plants  more  efficiently,  thereby  saving  money.  Using  the  humidification  pad,  water treatment is not required – simply connect to the d rinking water supply, that's it! Only fresh water is applied, there  is  no  recirculation  and  thus  no  vapour  and  no  aerosol  output.  The  available  Güntner  Hydro Management  GHM  pad  monitors  operating  states  for  the  best  adjustment  between  fan  speed  and humidif ication  of  the  pad.  In  dry  operation,  the  GHM pad  ensures  the  regular  drain  of  the  unit  and  of  the supply for hygiene reasons.

Gas cooler with HydroPad: Extending the subcritical operation period

The  V - SHAPE  Compact  gas  cooler  with  HydroPad  system  now  off ers  a  solution  to  push  the  CO 2 equator southwards:  The  adiabatic  pre - cooling  of  the  ambient  inlet  air  significantly  reduces  the  plant's  transcritical operating times. Especially in areas  where high temperatures and, at the same time, low humidity prevails, the "adiabatic potential" is huge! 2 High capacity, tested for safety The  V - SHAPE  Compact  coolers  are  equipped  with  retractable  crane  lugs  and  allow  for  particularly  easy installation  and  quick  mounting.  The  solid  units  with  their  compact  casings  made  of powder - coated, galvanised steel are extensively tested for stability; they are, for instance, subjected to lifting tests to assess the torsional stiffness and to load tests to determine the snow and wind load and the resistance of structures to  earthquakes .  The  capacity  ranges  from  13  kW  up  to  several  hundred  kW;  this  means  that  CO 2 units operated  in  dry  mode  can  achieve  capacities  of  up  to  560  kW.  The  heat  exchangers  optimised  for  this refrigerant are designed for an operating pressure of up to 120 bar as a standard.

High - capacity fans, suitable control concepts

Up to four fans are available per unit in AC and EC technology and with a diameter of 630 mm and 800 mm. It goes without saying that every fan complies with the current requirements of the ErP Dire ctive. For every fan variant, we offer the suitable control concept including the intelligent Güntner Hydro Management GHM pad  that  always  choses  the  most  cost - efficient  mode  of  operation  and,  in  wetted  operation,  always  applies only as much water as can e vaporate under the respective conditions. Some fan types can also be controlled via voltage (0 – 10 V) or current signal (4 – 20 mA).

Accessory range for Compact units

The V - SHAPE family provides the common Güntner Compact standard regarding technical ac cessories such as flange/threaded connections,  a 1“  ball valve for  ventilation and drain respectively, a multiple circuit coil, an integrated subcooler with or without tubing, and epoxy resin - coated fins. In addition, mounted parts such as controls/control panels,  safety switches and  vibration dampers are also available. What's more, we also offer the adiabatic HydroPad pre - cooling system which is made possible thanks to the V - shape arrangement of the coils. This accessory is the highlight of all the option s for this product family!
