2. Description of accessories
a. Steps or stepless capacity control system
Please refer to chapter 2.6 and 2.7 for the detail of step or stepless capacity control system.
b. Compatible steps and stepless capacity control system
For customers’ ease of stock control, possible modification of capacitycontrol logic in the future, or other special
requirements of capacity control, Hanbell deliberately designs devices for stepless/step dual capacity control as
nonstandard accessory for customers’ choices. Logic of stepless/step dual capacity control is basically identical to
those of stepless or step capacity control respectively. Please refer to Chapter 2.6, 2.7, & 2.8 for further details.
c. Suction and discharge check valve
Hanbell standard check valve (vertical type) is gravitydriven with characteristics of large flow volume and low
pressure differential. After shutdown of compressor, Teflon taper guider inside can simultaneously seal up the
precisely machined base of check valve by gravity force to effectively prevent return of highpressured gas to
compressor. The gravitydriven check valve is equipped vertically. Due to limitation of space or piping requirements,
alternative horizontal check valve is also available.
