You need one machine for mortar, another for gypsum, and yet another for applying the fireproof layer; while a 380V industrial power supply at the site makes things manageable, the equipment simply fails to operate on projects limited to 220V residential power. Even more troublesome is the spray quality—insufficient adhesion and poor density lead to hollow spots and cracking; one round of rework wipes out your entire profit.

Derutu DP-220 Multifunctional Shotcrete Machine

Designed specifically to address the three major pain points of engineering spraying—excessive equipment requirements, compatibility challenges, and inconsistent quality—this single unit handles the application of diverse materials and adapts to all scenarios with dual-voltage capability. It ensures dense, void-free coating and features a split-unit design that excels in both safety and ease of operation, making it an essential tool for engineering teams looking to cut costs, boost efficiency, and expand their business scope.

Versatile machine: fully compatible with mortar, gypsum, and fire-resistant coatings.

The DP-220 features a high-performance screw pump and a highly adaptable material delivery system, enabling the spraying of mainstream materials used in construction projects:

*Cement mortar: Suitable for foundational tasks such as interior and exterior wall plastering and floor leveling; ensures continuous, stable output and smooth pumping even with coarse-grained mortar;

*Gypsum materials: Lightweight plastering gypsum, base-coat leveling gypsum, and finish-coat gypsum; delivers uniform atomization and strong adhesion;

*Fire-resistant coatings: Specialized applications such as fire-resistant coatings for steel structures and tunnel fireproofing layers; allows for controlled thickness and produces a dense coating;

Dual-voltage adaptive (220V/380V): simply plug in and start working upon arrival at the site.

Equipped with a standard dual-voltage adaptive system, the unit connects directly to both 220V residential and 380V industrial power supplies—no transformers or rewiring required. Simply plug it in and get to work, completely eliminating power supply constraints; it handles everything from large-scale projects to small jobs, effectively doubling your team's service scope so you never have to turn down a project due to voltage incompatibility.

Adjustable spraying flow rate: freely adjust the coating thickness.

The DP-220 utilizes high-pressure pumping and atomized spraying technology, allowing for adjustable spray flow rates. Upon application, the material deeply penetrates the pores of the wall substrate, creating a mechanical interlock that delivers more than double the bond strength of manual application; this fundamentally eliminates the risks of hollow spots and detachment.

The DP-220 features a split-unit design that physically separates the electrical control system from the material delivery system, thereby eliminating the risk of short circuits or electrical leakage caused by material seepage. Equipped with multiple safety mechanisms—including overload protection, undervoltage protection, and an emergency stop button—the unit ensures safe and controlled operation throughout the job, providing greater peace of mind regarding electrical safety and personnel protection on the worksite.
