Shell and tube heat exchangers
The wide range of shell and tube heat exchangers meets the application needs of countless sectors: from refrigeration (evaporators and condensers, suitable for various types of refrigerants such as R22, R134a, R410A, R407C, NH3 etc.) to industrial applications such as liquid/liquid, oil cooling etc.
Power from 10 to 10000 kW.
Dry expansion evaporators FSE
FSE S&T
The models of the FSE series, optimized for use with R134a and R1234ze, can be used with all commonly used refrigerants; through the selection software and the support of our Technical Office it will be possible to obtain the best solution for every working condition.
The SDK Group shell and tube evaporators of the FSE series have a cooling capacity of up to 2200 kW, and up to 4 refrigerant circuits.
LSE Dry Expansion Evaporators
LSE S&T
The main applications of LSE dry expansion evaporators are water cooling in air conditioning systems, cooling of liquids or non-freezing mixtures in refrigeration systems, hot water production in heat pump systems.
The LSE series evaporators guarantee better thermodynamic performance by creating a precise configuration of the counter-current motion and the reduction of by-passes through tight manufacturing and coupling tolerances.
SSE Dry Expansion Evaporators
SSE S&T
The SSE series models, optimized for use with R134a and R1234ze, can be used with all commonly used refrigerants; through the selection software and the support of our Technical Office it will be possible to obtain the best solution for every working condition.
The SDK Group shell and tube evaporators of the SSE series have a cooling capacity of up to 2200 kW, and up to 4 refrigerant circuits.
Liquid receivers RL & RL-V
RL & RL-V S&T
The main applications of our liquid receivers are the containment of the refrigerant charge in case of intervention on the system and the absorption of the system load variations.
The RL and RL-V liquid receivers have an accumulation capacity between 5 and approximately 760 liters.
Receivers up to 5000 liters are made on request (contact our Sales Office).
Two series are available:
Horizontal liquid receivers RL .
Vertical liquid receivers RL-V.
Capacitors B (Europe market)
B S&T (EU market)
The SDK Group “ B “condenser product family has been designed for air conditioning and process cooling applications using HFC and HFO refrigerants as primary fluid, the secondary fluid is usually water or glycols.
Thanks to an high thermal performance tube the B condenser has a compact design reducing the refrigerant charge of about – 35% vs traditional condensers with a competitive market price.
The capacity range is from 50 to 1500 kW, custom models are also available for higher capacity demands.
Two model range are available at 30 and 45 barg on shell side, tube side is at 10 bargThe standard configuration is 2 passes with tube length 1850 mm.
Oil coolers oil
OIL S&T
The SDK Group oil coolers are designed for maximum pressures of 30 bar for the oil side and 10 for the water side.
The dimensions range from a minimum diameter of 141 mm to a maximum of 324 mm, the lengths reach up to 2600 mm.
Marine condensers M - SM
M - SM S&T
The “M” series shell and tube marine condensers have a thermal capacity, at Eurovent conditions, between 35 and 750 kW for catalogue models.
All condensers are equipped with service connections and safety valve.
The standard construction of the “M” series shell and tube marine condensers includes the use of the following materials:
carbon steel heads internally lined with seawater resistant coating
SBR collar
carbon steel tube plates with seawater resistant coating,
carbon steel shell
CuNi 90/10 alloy tubes
