ENCOsys is engineered to transfer heat from steam to a water loop. PREsys functions as a pressure-reducing station for steam and other compatible fluids. CONAsys is a pre-assembled condensate drainage station. Each serves a distinct operational purpose and can be seamlessly integrated within the same steam network.

Pre-Assembled Packages
Complete systems rather than individual components
In a steam system, overall performance depends as much on equipment integration as it does on individual component selection. Depending on your project requirements, ARI solutions bring together heat exchangers, control valves, steam traps, instrumentation, and accessories. ENCOsys, PREsys, and CONAsys fulfill three distinct functions: heat transfer, pressure reduction, and condensate discharge.
01
Process Engineering Study
Definition of operating conditions, flow rates, pressures, and temperatures prior to equipment selection.
02
Integration
Integration of industrial valves, heat exchange, instrumentation, and control solutions tailored to your system's operational requirements.
03
Assembly
Custom-engineered packages designed to streamline interfacing and installation, featuring modular pre-assembly tailored to your project's scope.
04
Canadian Project
Piping connections and technical documentation engineered for Canadian facilities.

Selecting between ENCOsys, PREsys, and CONAsys
These systems do not perform the same function. Proper selection begins with a comprehensive review of your process mass balance and site interfaces, not pipe diameter alone.
Intended Function
ENCOsys · Exchange
Transfer heat from steam to water with precise secondary temperature control.
PREsys · Pressure Reduction
Reduce steam pressure to an optimal operating pressure engineered for downstream equipment.
CONAsys · Steam Trapping
Consolidate the condensate drainage system into an accessible, installation-ready station.

Where can ARI pre-assembled systems be utilized?
ENCOsys, PREsys, and CONAsys operate at key stages throughout industrial steam systems, spanning hot water generation and pressure reduction to reliable condensate evacuation.
ENGINEERING & INTEGRATION
Engineered around an integrated ARI assembly
A pre-assembled system involves far more than just its skid: boundary conditions, control elements, and installation requirements must be clearly defined to establish the complete technical scope.
Instrumentation & Control
Depending on the system: control valve or pressure reducing valve, sensors, controller, and control panel integrated within the agreed scope.
Valves and Interface Solutions
Isolation valves, steam traps, accessories, connections, and maintenance access points tailored to your facility layout.
