Triple Preheater & Quadruple Preheater

Core Advantages

This TPH|QPH-X5R Triple/Quadruple Preheater is a high-performance heating solution for corrugated board production, with key advantages:

1. Passed national pressure vessel inspection and holds a safe use certificate, ensuring full compliance with industrial safety standards.

2. Electrically adjustable preheating range (60°–330°) and motor-with-brake power enable precise, stable temperature control for consistent paper heating.

3. Equipped with 3 turbine reducers and gear-driven swing arms, ensuring smooth, uniform operation of preheating rolls.

4. A total of 9 steel-paper guide rolls (5 fixed, 4 free, with optional balancing rollers) ensure even paper feeding and heating distribution.

Application & User-Focused Design

It supports 2200–3300mm production widths, with a max 375m/min production speed (450m/min design speed). It addresses user pain points:

1. Double/single cavity pre-heat roll options adapt to varying heating intensity requirements for different paper types.

2. Constant/sync/fixed sync speed modes match diverse corrugator line configurations and production rhythms.

3. Two-part superimposed structure (top layer mountable on glue machines) enables independent or combined operation, improving line flexibility.

Why Choose This Preheater?

1. Compatible with standard factory utilities (10–12kg/cm² steam; AC380V 50Hz 3PH power).

2. Constant-speed preheating rolls with bearings and reducers ensure uniform heating, reducing cardboard defects and waste.

3. It balances safety compliance, flexible operation, and high-speed performance—ideal for medium-to-large corrugated production lines.
