Piston Transport Compressors

Product catalog summary

Introduction
The TRANSPORT series by OFFICINE MARIO DORIN S.p.A. is designed for transport applications where low weight and compact dimensions are crucial. It includes two ranges of open-type compressors with aluminum bodies: 0T and 4D. The 0T range features 2-cylinder compressors with displacements from 1.36 to 4.76 m3/h and a weight of only 6 kg. The 4D range includes 4-cylinder compressors with swept volumes between 492 and 733 cm3 and displacements from 15 to 154 m3/h.

Main Features

High reliability with rolling bearings on both hubs, robust shaft, connection rods, and piston pins, and a new shaft seal design.
Quiet operation across all application ranges and compressor speeds.
Easy maintenance.
Extremely low weight and compact design.
Wide range of compressor speeds and high efficiency.
Optimized internal fluid dynamics for new low GWP refrigerants.

The 4D range also offers a reversible lobe oil pump, optional 50% capacity control, an internal safety valve, and the possibility of a magnetic clutch.

Technical Data
The document provides detailed technical specifications, including cylinder count, bore, stroke, swept volume, displacement, oil charge, weight, and suction and discharge line dimensions for various models. Optional accessories and application limits are also outlined.

Application Limits
Standard operation and maximum superheating of 20K are specified for different refrigerants, including R134a and R404A/R507, with corresponding evaporation and condensing temperature ranges.

Performance Data
Performance data is based on European Standard EN12900, with suction gas temperature at 20°C and compressor speed at 1450 rpm. The document includes tables of refrigerating capacity and shaft power for various temperature conditions.

Overall Dimensions
Figures and descriptions of the overall dimensions and components such as oil sight, oil charge plug, pressure taps, and service valves are provided for different models.
