Warehouse Dry Store, finished goods



In 2007 Torresan Estate opened the doors to their environmentally friendly, state of the art, contract bottling facility situated in McLaren Vale which services the needs of the McLaren Vale Wine region and further afield.

The purpose built facility has 2 lines in operation with a capacity to bottle 14,000 cases of wine per 8 hour shift. With their brand new larger line in place, it is the first fully automated bottling line in the region capable of bottling over 14,000 bottles per hour in combination with the smaller premium line that has a capacity of 8,000 bottles per hour. Servicing the bottling facility are three finished goods storage areas including a primary 3,000 square metre warehouse, a secondary warehouse of 4,800 sqm and a brand new 4,500 sqm facility.

Project Requirements

Torresan Estate required a climate control solution for their expansive finished goods warehouse that delivered the below requirements:

  • Minimal energy consumption
  • Maintain targeted temperature within the warehouse between 18 – 20°C
  • Maintain target temperature along the full height of the storage racks
  • Maintain the Ambient relative humidity within the building at 65%



Ambient DB (°C) 36.4
Ambient WB (°C) 18.1
Space Temp. (°C) 18-20
Relief Temp. (°C) 20
Model CW-80S
No. of Units 2
Supply Air Temp. (°C) 13.5
Total Standalone Cooling Capacity (kW) 105.2
Standalone Cooling COP 5.3
Project Deliverables

Two Climate Wizard CW-80S units were installed to achieve precise temperature and humidity control within the warehouse; enabling Torresan Estate to ensure consistent quality at a very low cooling cost.

Climate Wizard has the capability to maintain the 65% relative humidity specified. By pairing this with external cue points on the building, facilities management have full capability to control the environment to precise temperatures and humidity levels.

Selecting Climate Wizard over a traditional refrigerated air conditioning system meant there was not a requirement for an electrical upgrade to satisfy 71.5kW of input power compared to the two units only needing 20kW. In addition to this upfront cost reduction, Torresan Estate are seeing less energy consumption compared to if a traditional refrigerated air conditioning system was installed.


Being able to maintain optimal conditions within the dry store for finished goods all year round, particularly during periods of extreme heat, added another dimension to the exceptional level of service provided by Torresan Estate to its customers. This gives greater assurance to maintaining the quality of the wine being bottled and stored.

Climate Wizard Supercool capability is not affected during periods of extreme heat, where ambient dry bulb temperatures reach up to 50oC.

Table 1 outlines the energy savings for the installation, extrapolated over a 12 month period. Input power savings for the installation have been calculated as per Table 2.

Energy consumed by equivalent refrigerant system (kWh) 82,467
Energy consumed by 2 x CW-80S (kWh) 29,531
Energy saved (kWh) 52,936

Below is a snapshot showing how Climate Wizard successfully maintains target temperature within the warehouse during periods of extreme heat.


We have searched for an optimal solution for temperature and humidity regulation for storage of our customer’s premium finished goods. All of our storage areas are partially buried into the side of the natural landscape to help with maintaining even temperature stabilisation.  For 8-9 months of the year this design was maintaining adequate control, however with forever increasing periods of summer temperature spikes we needed a solution to maintain this stable state year round. This solution had to be cost and energy efficient in line with our core company environmental values and beneficial to our customers service needs.

After investigating various solutions, Climate Wizard by Seeley International was chosen and we have been extremely happy with results that the units have provided us. The install utilises a smart control system of activation and once the desired temperature and humidity set points are inputted it automatically turns the units on or off to reach the desired levels. We no longer have temperature spikes, even on days of 35-40 degs C, the system is able to maintain even stable temperatures around 18 degrees year round and at a low running cost. Part of the project also involved installing low cost recirculation fans to even out temperature levels between the upper and lower pallet stack levels. Overall, we have been very satisfied with the results and would happily recommend this technology as an excellent climate control solution.
