FINNED TUBE SOLUTIONS

Whether it be for residential or commercial use such as large greenhouses or botanical gardens , zoos , museums or churches , Turnbull & Scott offer highly effective Finned Tube heating systems .
Below are some of the different environments and buildings which Turnbull & Scott have provided solutions for in the past .
SPECIALIST GREENHOUSE ENVIRONMENTS
Turnbull & Scott provide heating solutions for many specialist environments , including for plants and wildlife , to ensure that optimum temperatures are achieved as required for each setting .
The stimulation of plant growth in botanical environments is a precise and delicate process . The heating system must deliver a consistent ambient temperature as required by specific species .
ROYAL BOTANIC GARDENS , EDINBURGH
The Royal Botanic Gardens ( RBGE ) has revealed its vision for Edinburgh Biomes , an ambitious new project to protect its unique and globally important plant collection . To help achieve their vision , the RBGE required a highly reliable and efficient heating system that could withstand the test of time whilst providing the optimal environment temperature to promote the growth and development of plant life .
OUR SOLUTION :
With the overall project concept being around building for the future , it was essential that a sturdy heating system was in place . A galvanised finned tube heating solution was chosen to meet the exacting requirements .
Natural convection heating is preferred in this environment over forced convection due to the fragile nature of the plants .
To deliver the required heat , the project required a variety of tube lengths with three different tube diameters : 50mm nominal bore ( NB ), 65mm NB and 80mm NB . All tubes were fitted with 25mm steel fins with a 10mm fin pitch separating each fin . They were finished with a hot dipped galvanized coating to prevent corrosion . Overall , over 270m of tube length was required for this project .
To optimise space in the greenhouses , this solution included a combination of using wall attached wall-bracketed Finned Tube and trench encased Finned Tube in areas where space was limited .
